Description
The TLV320AIC3120 device is a low-power, highly integrated, high-performance codec which features a
mono audio DAC and mono audio ADC.
The TLV320AIC3120 device features a high-performance audio codec with 24-bit mono playback and
mono record functionality. The device integrates several analog features, such as a microphone interface,
headphone drivers, and speaker drivers. The TLV320AIC3120 device has a fully programmable miniDSP
for digital audio processing. The digital audio data format is programmable to work with popular audio
standard protocols (I2S, left-justified and right-justified) in master, slave, DSP, and TDM modes. Bass
boost, treble, or EQ are supported by the programmable digital signal-processing blocks (PRB). An onchip PLL provides the high-speed clock needed by the digital signal-processing block. The volume level is
controlled either by pin control or by register control. The audio functions are controlled using the I2C serial
bus.
The TLV320AIC3120 device is available in a 32-pin VQFN package.

To minimize battery-current leakage, the SPKVDD voltage level must not be below the AVDD voltage level.
All grounds on board are tied together, so they must not differ in voltage by more than 0.2-V maximum for any combination of ground
signals. By use of a wide trace or ground plane, ensure a low-impedance connection between HPVSS and DVSS.
The maximum input frequency must be 50 MHz for any digital pin used as a general-purpose clock.

Ratio of output level with 1-kHz full-scale sine-wave input, to the output level with the inputs short-circuited, measured A-weighted over a
20-Hz to 20-kHz bandwidth using an audio analyzer.
All performance measurements done with 20-kHz low-pass filter and, where noted, A-weighted filter. Failure to use such a filter may
result in higher THD+N and lower SNR and dynamic range readings than shown in the Electrical Characteristics. The low-pass filter
removes out-of-band noise, which, although not audible, may affect dynamic specification values.
DAC to headphone-out PSRR measurement is calculated as PSRR = 20 × log(ΔVHPOUT / ΔVHPVDD).

Feature Description
Power-Supply Sequence
The TLV320AIC3120 requires multiple power supply rails for operation. All the power rails must be
powered up for the device to operate at the fullest potention. The following is the recommended power-up
sequencing for proper operation:
1. Power up SPKVDD
2. Power up IOVDD
3. Power up DVDD shortly after IOVDD
4. Power up AVDD and HPVDD
Although not necessary, if the system requires, during shutdown, remove the power supplies in the
reverse order of the above sequence.

7.3.2
www.ti.com
Reset
The TLV320AIC3120 internal logic must be initialized to a known condition for proper device function. To
initialize the device to its default operating condition, the hardware reset pin (RESET) must be pulled low
for at least 10 ns. For this initialization to work, both the IOVDD and DVDD supplies must be powered up.
TI recommends that while the DVDD supply powers up, the RESET pin is pulled low.
The device can also be reset via software reset. Writing a 1 into page 0 / register 1, bit D0 resets the
device.
7.3.3
Device Start-Up Lockout Times
After the TLV320AIC3120 is initialized through hardware reset at power up or software reset, the internal
memories are initialized to default values. This initialization takes place within 1 ms after pulling the
RESET signal high. During this initialization phase, no register-read or register-write operation should be
performed on ADC or DAC coefficient buffers. Also, no block within the codec should be powered up
during the initialization phase.
7.3.4
PLL Start-Up
Whenever the PLL is powered up, a start-up delay of approximately of 10 ms occurs after the power-up
command of the PLL and before the clocks are available to the codec. This delay is to ensure stable
operation of the PLL and clock-divider logic.
7.3.5
Power-Stage Reset
The power-stage-only reset is used to reset the device after an overcurrent latching shutdown has
occurred. Using this reset re-enables the output stage without resetting all of the registers in the device.
Each of the two power stages has its own dedicated reset bit. The headphone power-stage reset is
performed by setting page 1 / register 31, bit D7 for HPOUT. The speaker power-stage reset is performed
by setting page 1 / register 32, bit D7 for SPKP and SPKM.
7.3.6
Software Power Down
By default, all circuit blocks are powered down following a reset condition. Hardware power up of each
circuit block can be controlled by writing to the appropriate control register. This approach allows the
lowest power-supply current for the functionality required. However, when a block is powered down, all of
the register settings are maintained as long as power is still being applied to the device.
7.3.7
Audio Analog I/O
The TLV320AIC3120 has a mono audio DAC and a mono ADC. The device supports a wide range of
analog interfaces to support different headsets and analog outputs. The TLV320AIC3120 has features to
interface output drivers (8-Ω, 16-Ω, 32-Ω) and a microphone PGA with AGC control.
7.3.8
miniDSP
The TLV320AIC3120 device features two miniDSP cores. The first miniDSP core is tightly coupled to the
ADC; the second miniDSP core is tightly coupled to the DAC. The fully programmable algorithms for the
miniDSP must be loaded into the device after power up. The miniDSPs have direct access to the digital
audio stream on the ADC and on the DAC side, offering the possibility for advanced, very low-group-delay
DSP algorithms.
The ADC miniDSP has 384 programmable instructions, 256 data memory locations, and 128
programmable coefficients. The DAC miniDSP has 1024 programmable instructions, 896 data memory
locations, and 512 programmable coefficients (in the adaptive mode, there are two banks of 256
programmable coefficients each).

Digital Processing Low-Power Modes
The TLV320AIC3120 device can be tuned to minimize power dissipation, to maximize performance, or to
an operating point between the two extremes to best fit the application. The choice of processing blocks,
PRB_P1 to PRB_P25 for mono playback and PRB_R4 to PRB_R18 for mono recording, also influences
the power consumption. In fact, the numerous processing blocks have been implemented to offer a choice
among configurations having a different balance of power optimization and signal-processing capabilities.

7.3.10 Audio ADC and Analog Inputs
7.3.10.1 MICBIAS and Microphone Preamplifier
The TLV320AIC3120 device includes a microphone bias circuit that sources up to 4 mA of current and is
programmable to a 2-V, 2.5-V, or AVDD level. The level is controlled by writing to page 1 / register 46, bits
D1–D0. Table 7-9 lists this functionality.

During normal operation, MICBIAS can be set to 2.5 V for better performance. However, based on the
model of the selected microphone, optimal performance can be obtained at another setting and therefore
the performance at a given setting must be verified.
The lowest current consumption occurs when MICBIAS is powered down. The next-lowest current
consumption occurs when MICBIAS is set at AVDD. The highest current consumption occurs when
MICBIAS is set at 2 V.
Because of the oversampling nature of the audio ADC and the integrated digital-decimation filtering,
requirements for analog anti-aliasing filtering are very relaxed. The TLV320AIC3120 device integrates a
second-order analog anti-aliasing filter with 20-dB attenuation at 1 MHz. This filter, combined with the
digital decimal filter, provides sufficient anti-aliasing filtering without requiring any external components.

The MIC PGA supports analog gain control from 0 dB to 59.5 dB in steps of 0.5 dB. These gain levels are
controlled by writing to page 1 / register 47, bits D6–D0. The PGA gain changes are implemented with
internal soft-stepping. This soft-stepping ensures that volume-control changes occur smoothly with no
audible artifacts. On reset, the MIC PGA gain defaults to a mute condition, with soft-stepping enabled. The
ADC soft-stepping control is enabled or disabled by writing to page 0 / register 81, bits D1–D0. ADC softstepping timing is provided by the internal oscillator and internal divider logic block.
The input feed-forward resistance for the MIC1LP input of the microphone PGA stage has three settings,
10 kΩ, 20 kΩ, and 40 kΩ, which are controlled by writing to page 1 / register 48, bits D7 and D6. The input
feed-forward resistance value selected affects the gain of the microphone PGA. The ADC PGA gain for
the MIC1LP input depends on the setting of page1 / register 48 and page 1 / register 49, bits D7–D6. If
D7–D6 are set to 01, then the ADC PGA has 6 dB more gain with respect to the value programmed using
page 1 / register 47. If D7–D6 are set to 10, then the ADC PGA has the same gain as programmed using
page 1 / register 47. If D7–D6 are set to 11, then the ADC PGA has 6 dB less gain with respect to the
value programmed using page 1 / register 47. The same gain scaling is also valid for the MIC1RP and
MIC1LM input, based on the feed-forward resistance selected using page 1 / register 48, bits D5–D2.

The MIC PGA gain is either controlled by an AGC loop or as a fixed gain. See for the various analog input
routings to the MIC PGA that are supported in the single-ended and differential configurations. The AGC is
enabled by writing to page 0 / register 86, bit D7. If the AGC is not enabled, then setting a fixed gain
occurs by writing to page 1 / register 47, bits D6–D0. Because the TLV320AIC3120 device supports softstepping gain changes, a read-only flag on page 0 / register 36, bit D7 is set whenever the gain applied by
PGA equals the desired value set by the gain register. The MIC PGA is enabled by writing to page 1 /
register 47, bit D7. ADC muting occurs by writing to page 0 / register 82, bit D7 and page 1 / register 47,
bit D7. Disabling the MIC PGA sets the gain to 0 dB. Muting the ADC causes the digital output to mute so
that the output value remains fixed. When soft-stepping is enabled, the CODEC_CLKIN signal must stay
active until after the ADC power-down register is written, in order to ensure that soft-stepping to mute has
had time to complete. When the ADC POWER UP flag is no longer set, the CODEC_CLKIN signal can
shut down.
7.3.10.2 Automatic Gain Control (AGC)
The TLV320AIC3120 includes automatic gain control (AGC) for the microphone inputs. AGC can be used
to maintain nominally constant output-signal amplitude when recording speech signals. This circuitry
automatically adjusts the MIC PGA gain as the input signal becomes overly loud or very weak, such as
when a person speaking into a microphone moves closer to or farther from the microphone. The AGC
algorithm has several programmable settings, including target gain, attack and decay time constants,
noise threshold, and maximum PGA applicable, that allow the algorithm to be fine-tuned for any particular
application. The algorithm uses the absolute average of the signal (which is the average of the absolute
value of the signal) as a measure of the nominal amplitude of the output signal. Because the gain can be
changed at the sample interval time, the AGC algorithm operates at the ADC_fS clock rate.

SLAS653C – FEBRUARY 2010 – REVISED FEBRUARY 2017
Target level represents the nominal output level at which the AGC attempts to hold the ADC output
signal. The TLV320AIC3120 allows programming of eight different target levels, which can be
programmed from –5.5 dB to –24 dB relative to a full-scale signal. Because the TLV320AIC3120 reacts to
the signal absolute average and not to peak levels, TI recommends that the target level be set with
enough margin to avoid clipping at the occurrence of loud sounds.
An AGC low-pass filter is used to help determine the average level of the input signal. This average level
is compared to the programmed detection levels in the AGC to provide the correct functionality. This lowpass filter is in the form of a first-order IIR filter. Programming this filter is done by writing to page 4 /
register 2 through page 4 / register 7. Two 8-bit registers are used to form the 16-bit digital coefficient as
shown on the register map. In this way, a total of six registers are programmed to form the three IIR
coefficients.
Attack time determines how quickly the AGC circuitry reduces the PGA gain when the input signal is too
loud. Programming the attack time is done by writing to page 0 / register 89, bits D7–D0.
Decay time determines how quickly the PGA gain is increased when the input signal is too low.
Programming the decay time is done by writing to page 0 / register 90, bits D7–D0.
Noise threshold is a reference level. If the input speech average value falls below the noise threshold,
the AGC considers it as a silence and hence brings down the gain to 0 dB in steps of 0.5 dB every sample
period and sets the noise-threshold flag. The gain stays at 0 dB unless the input speech signal average
rises above the noise-threshold setting. This ensures that noise is not amplified in the absence of speech.
The noise-threshold level in the AGC algorithm is programmable from –30 dB to –90 dB for the
microphone input. When the AGC noise threshold is set to –70 dB, –80 db, or –90 dB, the microphone
input maximum PGA applicable setting must be greater than or equal to 11.5 dB, 21.5 dB, or 31.5 dB,
respectively. This operation includes debounce and hysteresis to prevent the AGC gain from cycling
between high gain and 0 dB when signals are near the noise threshold level. When the noise-threshold
flag is set, the status of the gain applied by the AGC and the saturation flag must be ignored by the
system software. Programming the noise debounce is done by writing to page 0 / register 91, bits D4–D0.
Programming the signal debounce is done by writing to page 0 / register 92, bits D3–D0.
Max PGA applicable allows the user to restrict the maximum gain applied by the AGC. This can be used
for limiting PGA gain in situations where environmental noise is greater than the programmed noise
threshold. Microphone input maximum PGA can be programmed from 0 dB to 59.5 dB in steps of 0.5 dB.
Programming the maximum PGA gain allowed by the AGC is done by writing to page 0 / register 88,
bits D6–D0.
See Table 7-11 for various AGC programming options. AGC can be used only if the microphone input is
routed to the ADC channel.

7.3.10.3 Delta-Sigma ADC
The analog-to-digital converter has a delta-sigma modulator with an oversampling ratio (AOSR) up to 128.
The ADC can support a maximum output rate of 192 kHz.
ADC power up is controlled by writing to page 0 / register 81, bit D7. An ADC power-up condition can be
verified by reading page 0 / register 36, bit D6.
7.3.10.4 ADC Decimation Filtering and Signal Processing
The TLV320AIC3120 ADC channel includes built-in digital decimation filters to process the oversampled
data from the delta-sigma modulator to generate digital data at the Nyquist sampling rate with high
dynamic range. The decimation filter can be chosen from three different types, depending on the required
frequency response, group delay, and sampling rate.
7.3.10.4.1 ADC Processing Blocks
The TLV320AIC3120 offers a range of processing blocks which implement various signal processing
capabilities along with decimation filtering. These processing blocks give users the choice of how much
and what type of signal processing they may use and which decimation filter is applied.
The choices among these processing blocks allow the system designer to balance power conservation
and signal-processing flexibility. Less signal-processing capability reduces the power consumed by the
device. Table 7-12 gives an overview of the available processing blocks of the ADC channel and their
properties. The Resource Class (RC) column gives a relative indication of power consumption.
The signal processing blocks available are:
• First-order IIR
• Scalable number of biquad filters
• Variable-tap FIR filter
• AGC
The processing blocks are tuned for common cases and can achieve high anti-alias filtering or low group
delay in combination with various signal-processing effects such as audio effects and frequency shaping.
The available first-order IIR, biquad, and FIR filters have fully user-programmable coefficients.

Depending on the selected processing block, different types and orders of digital filtering are available. A
first-order IIR filter is always available, and is useful to filter out possible dc components of the signal
efficiently. Up to five biquad sections or, alternatively, FIR filters of up to 25 taps are available for specific
processing blocks. The coefficients of the available filters are arranged as sequentially indexed
coefficients.

7.3.10.4.4 ADC Digital Decimation Filter Characteristics
The TLV320AIC3120 offers three different types of decimation filters. The integrated digital decimation
filter removes high-frequency content and downsamples the audio data from an initial sampling rate of
AOSR × fS to the final output sampling rate of fS. The decimation filtering is achieved using a higher-order
CIC filter followed by linear-phase FIR filters. The decimation filter cannot be chosen by itself; it is implicitly
set through the chosen processing block.
The following subsections describe the properties of the available filters A, B, and C.
7.3.10.4.4.1 Decimation Filter A
This filter is intended for use at sampling rates up to 48 kHz. When configuring this filter, the oversampling
ratio of the ADC can either be 128 or 64. For highest performance, the oversampling ratio must be set
to 128.
Filter A can also be used for 96 kHz at an AOSR of 64.

7.3.10.4.5 ADC Data Interface
The decimation filter and signal processing block in the ADC channel pass 32-bit data words to the audio
serial interface once every cycle of ADC_fS. During each cycle of ADC_fS, a pair of data words (for left
and right channel) is passed. The audio serial interface rounds the data to the required word length of the
interface before converting to serial data. Because the TLV320AIC3120 has only a mono ADC, it passes
the same data to both the left and right channels of the audio serial interface.
7.3.10.5 Updating ADC Digital Filter Coefficients During Record
When it is required to update the ADC digital filter coefficients during record, care must be taken to avoid
click and pop noise or even a possible oscillation noise. These artifacts can occur if the ADC coefficients
are updated without following the proper update sequence. The correct sequence is shown in Figure 7-15.
The values for the times listed are conservative and should be used for software purposes.

When the digital microphone mode is enabled, the analog section of the ADC can be powered down and
bypassed for power efficiency. The AOSR value for the ADC channel must be configured to select the
desired decimation ratio to be achieved, based on the external digital microphone properties.
7.3.10.7 DC Measurement
The TLV320AIC3120 supports a highly flexible dc-measurement feature using the high-resolution
oversampling and noise-shaping ADC. This mode can be used when the ADC channel is not used for the
voice/audio record function. This mode can be enabled by programming page 0 / register 102, bit D7. The
converted data is 24 bits, using the 2.22 numbering format. The value of the converted data for the ADC
channel can be read back from page 0 / register 104 through page 1 / register 106. Before reading back
the converted data, page 0 / register 103, bit D6 must be programmed to 1 in order to latch the converted
data into the read-back registers. After the converted data is read back, page 0 / register 103, bit D6 must
be immediately reset to 0. In dc-measurement mode, two measurement modes are supported.
Mode A
In dc-measurement mode A, a variable-length averaging filter is used. The length of averaging filter D can
be programmed from 1 to 20 by programming page 0 / register 102, bits D4–D0. To choose mode A,
page 0 / register 102, bit D5 must be programmed to 0.

By programming page 0 / register 103, bit D5 to 1, the averaging filter is periodically reset after 2R number
of ADC_MOD_CLK periods, where R is programmed in page 0 / register 103, bits D4–D0. When page 0 /
register 103, bit D5 is set to 1, then the value of D should be less than the value of R. When page 0 /
register 103, bit D5 is programmed to 0, the averaging filter is never reset.
7.3.10.8 ADC Setup
The following paragraphs are intended to guide a user through the steps necessary to configure the
TLV320AIC3120 ADC.
Step 1
The system clock source (master clock) and the targeted ADC sampling frequency must be identified.
Depending on the targeted performance, the decimation filter type (A, B, or C) and AOSR value can be
determined:
• Filter A should be used for 48-kHz high-performance operation; AOSR must be a multiple of 8.
• Filter B should be used for up to 96-kHz operations; AOSR must be a multiple of 4.
• Filter C should be used for up to 192-kHz operations; AOSR must be a multiple of 2.
In all cases, AOSR is limited in its range by the following condition:
2.8 MHz < AOSR × ADC_fS < 6.2 MHz

SLAS653C – FEBRUARY 2010 – REVISED FEBRUARY 2017
Based on the identified filter type and the required signal processing capabilities, the appropriate
processing block can be determined from the list of available processing blocks (PRB_R4 to PRB_R18).
Based on the available master clock, the chosen AOSR and the targeted sampling rate, the clock divider
values NADC and MADC can be determined. If necessary, the internal PLL can add a large degree of
flexibility.
In summary, CODEC_CLKIN (derived directly from the system clock source or from the internal PLL)
divided by MADC, NADC, and AOSR must be equal to the ADC sampling rate ADC_fS. The
CODEC_CLKIN clock signal is shared with the DAC clock-generation block.
CODEC_CLKIN = NADC × MADC × AOSR × ADC_fS
To a large degree, NADC and MADC can be chosen independently in the range of 1 to 128. In general,
NADC should be as large as possible as long as the following condition can still be met:
MADC × AOSR / 32 ≥ RC
RC is a function of the chosen processing block and is listed in Table 7-20.
The common-mode voltage setting of the device is determined by the available analog power supply.
At this point, the following device specific parameters are known: PRB_Rx, AOSR, NADC, MADC, input
and output common-mode values. If the PLL is used, the PLL parameters P, J, D, and R are determined
as well.
Step 2

7.3.12 Audio DAC and Audio Analog Outputs
The mono audio DAC consists of a digital-audio processing block, a digital interpolation filter, a digital
delta-sigma modulator, and an analog reconstruction filter. This high oversampling ratio (typically DOSR is
between 32 and 128) exhibits good dynamic range by ensuring that the quantization noise generated
within the delta-sigma modulator stays outside of the audio frequency band. Audio analog outputs include
mono headphone, or lineouts, and mono class-D speaker outputs. Because the TLV320AIC3120 device
has only a mono DAC, it inputs the mono data from the left channel, the right channel, or a mix of the left
and right channels as [(L + R) ÷ 2], controlled by setting page 0 / register 63, bits D5–D4. See for the
signal flow.
7.3.12.1 DAC
The TLV320AIC3120 mono-audio DAC supports data rates from 8 kHz to 192 kHz. The audio channel of
the mono DAC consists of a signal-processing engine with fixed processing blocks, a programmable
miniDSP, a digital interpolation filter, a multibit digital delta-sigma modulator, and an analog reconstruction
filter. The DAC is designed to provide enhanced performance at low sampling rates through increased
oversampling and image filtering, thereby keeping quantization noise generated within the delta-sigma
modulator and signal images strongly suppressed within the audio band to beyond 20 kHz. To handle
multiple input rates and optimize power dissipation and performance, the TLV320AIC3120 device allows
the system designer to program the oversampling rates over a wide range from 1 to 1024 by configuring
page 0 / register 13 and page 0 / register 14. The system designer can choose higher oversampling ratios
for lower input data rates and lower oversampling ratios for higher input data rates.
The TLV320AIC3120 DAC channel includes a built-in digital interpolation filter to generate oversampled
data for the delta-sigma modulator. The interpolation filter can be chosen from three different types,
depending on required frequency response, group delay, and sampling rate.
DAC power up is controlled by writing to page 0 / register 63, bit D7 the mono channel. The mono-channel
DAC clipping flag is provided as a read-only bit on page 0 / register 39, bit D7.

7.3.12.1.1 DAC Processing Blocks
The TLV320AIC3120 device implements signal-processing capabilities and interpolation filtering through
processing blocks. These fixed processing blocks give users the choice of how much and what type of
signal processing they use and which interpolation filter is applied.
The choices among these processing blocks allow the system designer to balance power conservation
and signal-processing flexibility. Table 7-20 gives an overview of all available processing blocks of the
DAC channel and their properties. The resource-class column gives an approximate indication of power
consumption for the digital (DVDD) supply; however, based on the out-of-band noise spectrum, the analog
power consumption of the drivers (HPVDD) may differ.
The signal processing blocks available are:
• First-order IIR
• Scalable number of biquad filters
The processing blocks are tuned for common cases and can achieve high image rejection or low group
delay in combination with various signal-processing effects such as audio effects and frequency shaping.
The available first-order IIR and biquad filters have fully user-programmable coefficients.

7.3.12.1.3 DAC User-Programmable Filters
Based on the selected processing block, different types and orders of digital filtering are available. Up to
six biquad sections are available for specific processing blocks.
The coefficients of the available filters are arranged as sequentially-indexed coefficients in two banks. If
adaptive filtering is chosen, the coefficient banks can be switched in real time.
When the DAC is running, the user-programmable filter coefficients are locked and cannot be accessed
for either read or write.
However, the TLV320AIC3120 device offers an adaptive filter mode as well. Setting page 8 / register 1, bit
D2 = 1 turns on double buffering of the coefficients. In this mode, filter coefficients are updated through
the host and activated without stopping and restarting the DAC which enables advanced adaptive filtering
applications.

SLAS653C – FEBRUARY 2010 – REVISED FEBRUARY 2017
In the double-buffering scheme, all coefficients are stored in two buffers (buffers A and B). When the DAC
is running and the adaptive filtering mode is turned on, setting page 8 / register 1, bit D0 = 1 switches the
coefficient buffers at the next start of a sampling period. This bit is set back to 0 after the switch occurs. At
the same time, page 8 / register 1, bit D1 toggles.
The flag in page 8 / register 1, bit D1 indicates which of the two buffers is actually in use.
Page 8 / register 1, bit D1 = 0: buffer A is in use by the DAC engine; bit D1 = 1: buffer B is in use.
While the device is running, coefficient updates are always made to the buffer not in use by the DAC,
regardless of the buffer to which the coefficients have been written.

The coefficients of these filters are each 16-bit, 2s-complement format, occupying two consecutive 8-bit
registers in the register space. Specifically, the filter coefficients are in 1.15 (one dot 15) format with a
range from –1.0 (0x8000) to 0.999969482421875 (0x7FFF) as shown in Figure 7-11.

7.3.12.2 DAC Digital-Volume Control
The DAC has a digital-volume control block which implements programmable gain. Each channel has an
independent volume control that can be varied from 24 dB to –63.5 dB in 0.5-dB steps. The left-channel
DAC volume is controlled by writing to page 0 / register 65, bits D7–D0. The right-channel DAC volume
can be controlled by writing to page 0 / register 66, bits D7–D0. DAC muting and setting up a master gain
control to control both channels occurs by writing to page 0 / register 64, bits D3–D0. The gain is
implemented with a soft-stepping algorithm, which only changes the actual volume by 0.125 dB per input
sample, either up or down, until the desired volume is reached. The rate of soft-stepping is slowed to one
step per two input samples by writing to page 0 / register 63, bits D1–D0. Note that the default source for
volume-control level settings is control by register writes (page 0 / register 65 and page 0 / register 66 to
control volume). Use of the VOL/MICDET pin to control the DAC volume is ignored until the volume
control source selected has been changed to pin control (page 0 / register 116, bit D7 = 1). This
functionality is shown in .
During soft-stepping, the host does not receive a signal when the DAC has been completely muted. This
may be important if the host must mute the DAC before making a significant change, such as changing
sample rates. In order to help with this situation, the device provides a flag back to the host through a
read-only register, page 0 / register 38, bit D4 for the left channel and bit D0 for the right channel. This
information alerts the host when the part has completed the soft-stepping and the actual volume has
reached the desired volume level. The soft-stepping feature can be disabled by writing to page 0 /
register 63, bits D1–D0.
If soft-stepping is enabled, the CODEC_CLKIN signal must be kept active until the DAC power-up flag is
cleared. When this flag is cleared, the internal DAC soft-stepping process is complete, and
CODEC_CLKIN can be stopped if desired. (The analog volume control can be ramped down using an
internal oscillator.)

7.3.12.3 Volume Control Pin
The range of voltages used by the 7-bit SAR ADC is shown in Section 5.5.
The volume-control pin is not enabled by default but is enabled by writing 1 to page 0 / register 116, bit
D7. The default DAC volume control uses software control of the volume, which occurs if page 0 /
register 116, bit D7 = 0. Soft-stepping the volume level is set up by writing to page 0 / register 63, bits
D1–D0.
When the volume-pin function is used, a 7-bit Vol ADC reads the voltage on the VOL/MICDET pin and
updates the digital volume control by overwriting the current value of the volume control. The new volume
setting which has been applied because of a change of voltage on the volume control pin is read on
page 0 / register 117, bits D6–D0. The 7-bit Vol ADC clock source is selected on page 0 / register 116, bit
D6. The update rate is programmed on page 0 / register 116, bits D2–D0 for this 7-bit SAR ADC.

shows the VOL/MICDET pin connection and functionality.
As shown in Table 7-27, the VOL/MICDET pin has a range of volume control from 18 dB down to –63 dB,
and mute. However, if less maximum gain is required, then a smaller range of voltage must be applied to
the VOL/MICDET pin. Applying a smaller range of voltage occurs by increasing the value of R2 relative to
the value of (P1 + R1), so that more voltage is available at the bottom of P1. The circuit must also be
designed such that for the values of R1, R2, and P1 chosen, the maximum voltage (top of the
potentiometer) does not exceed AVDD/2 (see Figure 7-30). The recommended values for R1, R2, and P1
for several maximum gains are shown in Table 7-28. Note that in typical applications, R1 must not be 0 Ω,
as the VOL/MICDET pin must not exceed AVDD/2 for proper ADC operation.

7.3.12.4 Dynamic Range Compression
Typical music signals are characterized by crest factors, the ratio of peak signal power to average signal
power, of 12 dB or more. To avoid audible distortions due to clipping of peak signals, the gain of the DAC
channel must be adjusted so as not to cause hard clipping of peak signals. As a result, during nominal
periods, the applied gain is low, causing the perception that the signal is not loud enough. To overcome
this problem, dynamic range conpression (DRC) in the TLV320AIC3120 continuously monitors the output
of the DAC digital volume control to detect its power level relative to 0 dBFS. When the power level is low,
DRC increases the input signal gain to make it sound louder. At the same time, if a peaking signal is
detected, it autonomously reduces the applied gain to avoid hard clipping. This results in sounds more
pleasing to the ear as well as sounding louder during nominal periods.
The DRC functionality in the TLV320AIC3120 is implemented by a combination of processing blocks in the
DAC channel as described in Section 7.3.12.1.2.
DRC can be disabled by writing to page 0 / register 68, bits D6–D5.
DRC typically works on the filtered version of the input signal. The input signals have no audio information
at dc and extremely low frequencies; however, they can significantly influence the energy estimation
function in the dynamic range compressor (the DRC). Also, most of the information about signal energy is
concentrated in the low-frequency region of the input signal.
To estimate the energy of the input signal, the signal is first fed to the DRC high-pass filter and then to the
DRC low-pass filter. These filters are implemented as first-order IIR filters given by
HHPF (z) =
HLPF (z) =
N0 + N1z -1
215 - D1z -1
N0 + N1z
(6)
-1
215 - D1z -1
(7)
The coefficients for these filters are 16 bits wide in 2s-complement format and are user-programmable
through register write as given in Table 7-29.

The default values of these coefficients implement a high-pass filter with a cutoff at 0.00166 × DAC_fS,
and a low-pass filter with a cutoff at 0.00033 × DAC_fS.
The output of the DRC high-pass filter is fed to the processing block selected for the DAC channel. The
absolute value of the DRC LPF filter is used for energy estimation within the DRC.
The gain in the DAC digital volume control is controlled by page 0 / register 65 and page 0 / register 66.
When the DRC is enabled, the applied gain is a function of the digital volume control register setting and
the output of the DRC.
The DRC parameters are described in sections that follow.
7.3.12.4.1 DRC Threshold
DRC threshold represents the level of the DAC playback signal at which the gain compression becomes
active. The output of the digital volume control in the DAC is compared with the set threshold. The
threshold value is programmable by writing to page 0 / register 68, bits D4–D2. The threshold value can
be adjusted between –3 dBFS and –24 dBFS in steps of 3 dB. Keeping the DRC threshold value too high
may not leave enough time for the DRC block to detect peaking signals, and can cause excessive
distortion at the outputs. Keeping the DRC threshold value too low can limit the perceived loudness of the
output signal.
The recommended DRC threshold value is –24 dB.
When the output signal exceeds the set DRC threshold, the interrupt flag bits at page 0 / register 44,
bits D3–D2 are updated. These flag bits are sticky in nature, and are reset only after they are read back
by the user. The non-sticky versions of the interrupt flags are also available at page 0 / register 46,
bits D3–D2.
7.3.12.4.2 DRC Hysteresis
DRC hysteresis is programmable by writing to page 0 / register 68, bits D1–D0. These bits can be
programmed to represent values between 0 dB and 3 dB in steps of 1dB. DRC hysteresis provides a
programmable window around the programmed DRC threshold that must be exceeded for the disabled
DRC to become enabled, or the enabled DRC to become disabled. For example, if the DRC threshold is
set to –12 dBFS and the DRC hysteresis is set to 3 dB, then if the gain compression in the DRC is
inactive, the output of the DAC digital volume control must exceed –9 dBFS before gain compression due
to the DRC is activated. Similarly, when the gain compression in the DRC is active, the output of the DAC
digital volume control must fall below –15 dBFS for gain compression in the DRC to be deactivated. The
DRC hysteresis feature prevents the rapid activation and de-activation of gain compression in the DRC in
cases when the output of the DAC digital volume control rapidly fluctuates in a narrow region around the
programmed DRC threshold. By programming the DRC hysteresis as 0 dB, the hysteresis action is
disabled.
The recommended value of DRC hysteresis is 3 dB.

7.3.12.4.3 DRC Hold
DRC hold time is intended to slow the start of decay for a specified period of time in response to a
decrease in energy level. To minimize audible artifacts, TI recommends to set the DRC hold time to 0
through programming page 0 / register 69, bits D6–D3 = 0000.
7.3.12.4.4 DRC Attack Rate
When the output of the DAC digital volume control exceeds the programmed DRC threshold, the gain
applied in the DAC digital volume control is progressively reduced to avoid the signal from saturating the
channel. This process of reducing the applied gain is called attack. To avoid audible artifacts, the gain is
reduced slowly with a rate equaling the attack rate, programmable via page 0 / register 70, bits D7–D4.
Attack rates can be programmed from 4-dB gain change per 1/DAC_fS to 1.2207e–5-dB gain change
per 1/DAC_fS.
Attack rates should be programmed such that before the output of the DAC digital volume control can clip,
the input signal should be sufficiently attenuated. High attack rates can cause audible artifacts, and tooslow attack rates may not be able to prevent the input signal from clipping.
The recommended DRC attack rate value is 1.9531e–4 dB per 1/DAC_fS.
7.3.12.4.5 DRC Decay Rate
When the DRC detects a reduction in output signal swing beyond the programmed DRC threshold, the
DRC enters a decay state, where the applied gain in the digital-volume control is gradually increased to
programmed values. To avoid audible artifacts, the gain is slowly increased with a rate equal to the decay
rate programmed through page 0 / register 70, bits D3–D0. The decay rates can be programmed from
1.5625e–3 dB per 1/DAC_fS to 4.7683e–7 dB per 1/DAC_fS. If the decay rates are programmed too high,
then sudden gain changes can cause audible artifacts. However, if it is programmed too slow, then the
output may be perceived as too low for a long time after the peak signal has passed.
The recommended value of DRC decay rate is 2.4414e–5 dB per 1/DAC_fS.

7.3.12.5 Headset Detection
The TLV320AIC3120 device includes extensive capability to monitor a headphone, microphone, or
headset jack, to determine if a plug has been inserted into the jack, and then determine what type of
headset or headphone is wired to the plug. The device also includes the capability to detect a button
press, even, for example, when starting calls on mobile phones with headsets. Figure 7-31 shows the
circuit configuration to enable this feature.

Figure 7-31. Jack Connections for Headset Detection
Headset Detection is enabled by programming page 0 / register 67, bit D1. In order to avoid false
detections because of mechanical vibrations in headset jacks or microphone buttons, a debounce function
is provided for glitch rejection. For the case of headset insertion, a debounce function with a range of 32
ms to 512 ms is provided. This can be programmed through page 0 / register 67, bits D4–D2. For
improved button-press detection, the debounce function has a range of 8 ms to 32 ms by programming
page 0 / register 67, bits D1–D0.
The TLV320AIC3120 device also provides feedback to the user when a button press or a headset
insertion or removal event is detected through register-readable flags or through an interrupt on the I/O
pins. The value in page 0 / register 46, bits D5–D4 provides the instantaneous state of button press and
headset insertion. Page 0 / register 44, bit D5 is a sticky (latched) flag that is set when the button-press
event is detected. Page 0 / register 44, bit D4 is a sticky flag which is set when the headset insertion or
removal event is detected. These sticky flags are set by the event occurrence, and are reset only when
read. This requires polling page 0 / register 44. To avoid polling and the associated overhead, the
TLV320AIC3120 device also provides an interrupt feature, whereby events can trigger the INT1, the INT2,
or both interrupts. These interrupt events can be routed to one of the digital output pins. See
Section 7.3.12.6 for details.
The TLV320AIC3120 device not only detects a headset insertion event, but also is able to distinguish
between the different headsets inserted, such as stereo headphones or cellular headphones. After the
headset-detection event, the user can read page 0 / register 67, bits D6–D5 to determine the type of
headset inserted.

The headset detection block requires AVDD to be powered. The headset detection feature in the
TLV320AIC3120 device is achieved with very low power overhead, requiring less than 20 μA of additional
current from the AVDD supply.
7.3.12.6 Interrupts
Some specific events in the TLV320AIC3120 device that can require host processor intervention are used
to trigger interrupts to the host processor. This avoids polling the status-flag registers continuously. The
TLV320AIC3120 device has two defined interrupts, INT1 and INT2, that are configured by programming
page 0 / register 48 and page 0 / register 49. A user can configure interrupts INT1 and INT2 to be
triggered by one or many events, such as:
• Headset detection
• Button press
• DAC DRC signal exceeding threshold
• Noise detected by AGC
• Overcurrent condition in headphone drivers and speaker drivers
• Data overflow in the ADC and DAC processing blocks and filters
• DC measurement data available
Each of these INT1 and INT2 interrupts can be routed to output pins GPIO1 or DOUT. These interrupt
signals can either be configured as a single pulse or a series of pulses by programming page 0 /
register 48, bit D0 and page 0 / register 49, bit D0. If the user configures the interrupts as a series of
pulses, the events trigger the start of pulses that stop when the flag registers in page 0 / registers 44, 45,
and 50 are read by the user to determine the cause of the interrupt.
7.3.12.7 Key-Click Functionality With Beep Generator (PRB_P25)
A special algorithm has been included in the digital signal processing block PRB_P25 for generating a
digital sine-wave signal that is sent to the DAC.
This functionality is intended for generating key-click sounds for user feedback. The sine-wave generator
is very flexible (see Table 7-31) and is completely register programmable. Programming page 0 / register
71 through page 0 / register 79 (8 bits each) completely controls the functionality of this generator and
allows for differentiating sounds.
The two registers used for programming the 16-bit sine-wave coefficient are page 0 / register 76 and
page 0 / register 77. The two registers used for programming the 16-bit cosine-wave coefficient are
page 0 / register 78 and page 0 / register 79. This coefficient resolution allows virtually any frequency of
sine wave in the audio band to be generated, up to fS / 2.
The three registers used to control the length of the sine-burst waveform are page 0 / register 73 through
page 0 / register 75. The resolution (bit) in the registers of the sine-burst length is one sample time, so this
allows great control on the overall time of the sine-burst waveform. This 24-bit length timer supports
16 777 215 sample times. For example, if fS is set at 48 kHz, and the register value equals 96 000 d
(01 7700h), then the sine burst lasts exactly 2 seconds. The default settings for the tone generator, based
on using a sample rate of 48 kHz, are 1-kHz (approximately) sine wave, with a sine-burst length of five
cycles (5 ms).

volume is controlled by writing to page 0 / register 71, bits D5–D0. The right-channel volume is controlled
by writing to page 0, register 72, bits D5–D0. A master volume control that controls the left and right
channels of the beep generator are set up by writing to page 0 / register 72, bits D7–D6. The default
volume control setting is 2 dB, which provides the maximum tone-generator output level.
For generating other tones, the three tone-generator coefficients are found by running the following script
using MATLAB™ :
Sine = dec2hex(round(sin(2*π*Fin/Fs)*2^15))
Cosine = dec2hex(round(cos(2*π*Fin/Fs)*2^15))
Beep Length = dec2hex(floor(Fs*Cycle/Fin))
where,
Fin = Beep frequency desired
Fs = Sample rate
Cycle = Number of beep (sine wave) cycles that are required
dec2hex = Decimal to hexadecimal conversion function
NOTES:
1. Fin must be less than Fs / 4.
2. For the sine and cosine values, if the number of bits is less than the full 16-bit value, then the unused
MSBs must be written as 0s.
3. For the beep-length values, if number of bits is less than the full 24-bit value, then the unused MSBs
must be written as 0s.
Following the beep-volume control is a digital mixer that mixes in a playback data stream whose level has
already been set by the DAC volume control. Therefore, once the key-click volume level is set, the keyclick volume is not affected by the DAC volume control, which is the main control available to the end
user. shows this functionality.
Following the DAC, the signal can be further scaled by the analog output volume control and poweramplifier level control.
To insert a beep in the middle of an already-playing signal over DAC, use the following sequence.
Before the beep is desired, program the desired beep frequency, volume, and length in the configuration
registers. When a beep is desired, use the example configuration script.

# un-mute DAC to resume playing audio
Note that in this scheme the audio signal on the DAC is temporarily muted to enable beep generation.
Because powering down of NDAC clock divider is required, do not use the DAC_CLK or DAC_MOD_CLK
for generation of I2S clocks.
7.3.12.8 Programming DAC Digital Filter Coefficients
The digital filter coefficients must be programmed through the I2C interface. All digital filtering for the DAC
signal path must be loaded into the RAM before the DAC is powered on. Note that default ALLPASS filter
coefficients for programmable biquads are located in boot ROM. The boot ROM automatically loads the
default values into the RAM following a hardware reset (toggling the RESET pin) or after a software reset.
After resetting the device, loading boot ROM coefficients into the digital filters requires 100 μs of
programming time. During this time, reading or writing to page 8 through page 15 for updating DAC filter
coefficient values is not permitted. The DAC should not be powered up until after all of the DAC
configurations have been done by the system microprocessor.
7.3.12.9 Updating DAC Digital Filter Coefficients During PLAY
When it is required to update the DAC digital filter coefficients or beep generator during play, care must be
taken to avoid click and pop noise or even a possible oscillation noise. These artifacts can occur if the
DAC coefficients are updated without following the proper update sequence. The correct sequence is
shown in Figure 7-32. The values for times listed in Figure 7-32 are conservative and should be used for
software purposes.
There is also an adaptive mode, in which DAC coefficients can be updated while the DAC is on. For
details, see Section 7.3.12.1.3.

7.3.12.10 Digital Mixing and Routing
The TLV320AIC3120 has four digital mixing blocks. Each mixer can provide either mixing or multiplexing
of the digital audio data. The first mixer/multiplexer can be used to select input data for the mono DAC
from left channel, right channel, or a mix of the left and right channels [(L + R) / 2] . This digital routing can
be configured by writing to page 0 / register 63, bits D5–D4 for the DAC mono channel.
7.3.12.11 Analog Audio Routing
The TLV320AIC3120 has the capability to route the DAC output to either the headphone or the speaker
output. If desirable, both output drivers can operate at the same time while playing at different volume
levels. The TLV320AIC3120 provides various digital routing capabilities, allowing digital mixing or even
channel swapping in the digital domain. All analog outputs other than the selected ones can be powered
down for optimal power consumption.

7.3.12.11.1 Analog Output Volume Control
The output volume control fine tunes the level of the mixer amplifier signal supplied to the headphone
driver or the speaker driver. This architecture supports separate and concurrent volume levels for each of
the four output drivers. This volume control is also used as part of the output pop-noise reduction scheme.
This feature is available even if the ADC and DAC are powered down.
7.3.12.11.2 Headphone Analog-Output Volume Control
For the headphone outputs, the analog volume control has a range from 0 dB to –78 dB in 0.5-dB steps
for most of the useful range plus mute, which is shown in Table 7-33. This volume control includes softstepping logic. Routing the DAC output signal to the analog volume control occurs by writing to page 1 /
register 35, bit D7-D6.
Changing the analog volume for the headphone is controlled by writing to page 1 / register 36, bits
D6–D0. Routing the signal from the output of the analog volume control to the input of the headphone
power amplifier occurs by writing to page 1 / register 36, bit D7.
The analog volume-control soft-stepping time is based on the setting in page 0 / register 63, bits D1–D0.

7.3.12.12 Analog Outputs
Various analog routings are supported for playback. All the options can be conveniently viewed on the
functional block diagram, .
7.3.12.12.1 Headphone Drivers
The TLV320AIC3120 device features a mono headphone driver (HPOUT) that delivers up to 30 mW per
channel, at 3.3-V supply voltage, into a 16-Ω load. The headphones are used in a single-ended
configuration where an ac-coupling capacitor (dc-blocking) is connected between the device output pins
and the headphones. The headphone driver also supports 32-Ω and 10-kΩ loads without changing any
control register settings.
The headphone drivers can be configured to optimize the power consumption in the lineout-drive mode by
writing 11 to page 1 / register 44, bits D2–D1.
The output common mode of the headphone and lineout drivers is programmed to 1.35 V, 1.5 V, 1.65 V,
or 1.8 V by setting page 1 / register 31, bits D4–D3. Set the common-mode voltage to ≤ AVDD / 2.
The headphone driver can be powered on by writing to page 1 / register 31, bit D7. The HPOUT output
driver gain can be controlled by writing to page 1 / register 40, bits D6–D3, and it can be muted by writing
to page 1 / register 40, bit D2.
The TLV320AIC3120 device has a short-circuit protection feature for the headphone drivers, which is
always enabled to provide protection. The output condition of the headphone driver during short circuit is
programmed by writing to page 1 / register 31, bit D1. If D1 = 0 when a short circuit is detected, the device
limits the maximum current to the load. If D1 = 1 when a short circuit is detected, the device powers down
the output driver. The default condition for headphones is the current-limiting mode. In case of a short
circuit on either channel, the output is disabled and a status flag is provided as read-only bits on page 1 /
register 31, bit D0. If shutdown mode is enabled, then as soon as the short circuit is detected, page 1 /
register 31, bit D7 (for HPOUT) clears automatically. Next, the device requires a reset to re-enable the
output stage. Resetting occurs in two ways. First, the device master reset can be used, which requires
either toggling the RESET pin or using the software reset. If master reset is used, it resets all of the
registers. Second, a dedicated headphone power-stage reset can also be used to re-enable the output
stage, and that keeps all of the other device settings. The headphone power stage reset occurs by setting
page 1 / register 31, bit D7 for HPOUT. If the fault condition has been removed, then the device returns to
normal operation. If the fault is still present, then another shutdown occurs. Repeated resetting (more than
three times) is not recommended, as this could lead to overheating.
7.3.12.12.2 Speaker Drivers
The TLV320AIC3120 device has an integrated class-D mono speaker driver (SPKP / SPKM) capable of
driving an 8-Ω or 4-Ω differential load. The speaker driver can be powered directly from the battery supply
(2.7 V to 5.5 V) on the SPKVDD pins; however, the voltage (including spike voltage) must be limited below
the absolute-maximum voltage of 6 V.
The speaker driver is capable of supplying 400 mW per channel with a 3.6-V power supply. Through the
use of digital mixing, the device can connect one or both digital audio playback data channels to either
speaker driver; this also allows digital channel swapping if needed.
The class-D speaker driver can be powered on by writing to page 1 / register 32, bit D7. The class-D
output driver gain can be controlled by writing to page 1 / register 42, bits D4–D3, and it can be muted by
writing to page 1 / register 42, bit D2.
The TLV320AIC3120 device has a short-circuit protection feature for the speaker drivers that is always
enabled to provide protection. If the output is shorted, the output stage shuts down on the overcurrent
condition. (Current limiting is not an available option for the higher-current speaker driver output stage.) In
case of a short circuit on either channel, the output is disabled and a status flag is provided as a read-only
bit on page 1 / register 32, bit D0.

If shutdown occurs because of an overcurrent condition, then the device requires a reset to re-enable the
output stage. Resetting occurs in two ways. First, the device master reset can be used, which requires
either toggling the RESET pin or using the software reset. If master reset is used, it resets all of the
registers. Second, a dedicated speaker power-stage reset can be used that keeps all of the other device
settings. The speaker power-stage reset occurs by setting page 1 / register 32, bit D7 for SPKP and
SPKM. If the fault condition has been removed, then the device returns to normal operation. If the fault is
still present, then another shutdown occurs. Repeated resetting (more than three times) is not
recommended as this could lead to overheating.
To minimize battery current leakage, the SPKVDD voltage levels must not be less than the AVDD
voltage level.
The TLV320AIC3120 device has a thermal protection (OTP) feature for the speaker drivers which is
always enabled to provide protection. If the device overheats, then the output stops switching. When the
device cools down, the device resumes switching. An overtemperature status flag is provided as a readonly bit on page 0 / register 3, bit D1. The OTP feature is for self-protection of the device. If die
temperature can be controlled at the system or board level, then overtemperature does not occur.
7.3.12.13 Audio-Output Stage-Power Configurations
After the device has been configured (following a RESET) and the circuitry has been powered up, the
audio output stage can be powered up and powered down by register control.
These functions soft-start automatically. The two power stages can be powered up or powered down
independently..

7.3.12.14 DAC Setup
The following paragraphs are intended to guide a user through the steps necessary to configure the
TLV320AIC3120.
Step 1
The system clock source (master clock) and the targeted DAC sampling frequency must be identified.
Depending on the targeted performance, the decimation filter type (A, B, or C) and DOSR value can be
determined:
• Filter A should be used for 48-kHz high-performance operation; DOSR must be a multiple of 8.
• Filter B should be used for up to 96-kHz operations; DOSR must be a multiple of 4.
• Filter C should be used for up to 192-kHz operations; DOSR must be a multiple of 2.
In all cases, DOSR is limited in its range by the following condition:
2.8 MHz < DOSR × DAC_fS < 6.2 MHz
Based on the identified filter type and the required signal-processing capabilities, the appropriate
processing block can be determined from the list of available processing blocks (PRB_P1 to PRB_P25).

Based on the available master clock, the chosen DOSR and the targeted sampling rate, the clock-divider
values NDAC and MDAC can be determined. If necessary, the internal PLL can add a large degree of
flexibility.
In summary, CODEC_CLKIN (derived directly from the system clock source or from the internal PLL)
divided by MDAC, NDAC, and DOSR must be equal to the DAC sampling rate, DAC_fS. The
CODEC_CLKIN clock signal is shared with the DAC clock-generation block.
CODEC_CLKIN = NDAC × MDAC × DOSR × DAC_fS
To a large degree, NDAC and MDAC can be chosen independently in the range of 1 to 128. In general,
NDAC should be as large as possible as long as the following condition can still be met:
MDAC × DOSR / 32 ≥ RC
RC is a function of the chosen processing block and is listed in Table 7-20.
The common-mode voltage setting of the device is determined by the available analog power supply.
At this point, the following device-specific parameters are known: PRB_Rx, DOSR, NDAC, MDAC, input
and output common-mode values. If the PLL is used, the PLL parameters P, J, D, and R are determined
as well.
Step 2
Setting up the device via register programming:
The following list gives an example sequence of items that must be executed in the time between
powering the device up and reading data from the device. Note that there are other valid sequences,
depending on which features are used.

7.3.13 CLOCK Generation and PLL
The TLV320AIC3120 device supports a wide range of options for generating clocks for the ADC and DAC
sections as well as interface and other control blocks as shown in Figure 7-33. The clocks for the ADC
and DAC require a source reference clock. This clock is provided on a variety of device pins, such as the
MCLK, BCLK, or GPIO1 pins. The source reference clock for the codec is chosen by programming the
CODEC_CLKIN value on page 0 / register 4, bits D1–D0. The CODEC_CLKIN is then routed through
highly-flexible clock dividers shown in Figure 7-33 to generate the various clocks required for the ADC,
DAC, and digital processing sections. In the event that the desired audio or miniDSP clocks cannot be
generated from the reference clocks on MCLK, BCLK, or GPIO1, the TLV320AIC3120 device also
provides the option of using the on-chip PLL which supports a wide range of fractional multiplication
values to generate the required clocks. Starting from CODEC_CLKIN, the TLV320AIC3120 device
provides several programmable clock dividers to help achieve a variety of sampling rates for the ADC,
DAC.

The DAC modulator is clocked by DAC_MOD_CLK. For proper power-up operation of the DAC channel,
this clock must be enabled by configuring the NDAC and MDAC clock dividers (page 0 / register 11, bit D7
= 1 and page 0 / register 12, bit D7 = 1). When the DAC channel is powered down, the device internally
initiates a power-down sequence for proper shutdown. During this shutdown sequence, the NDAC and
MDAC dividers must not be powered down, or else a proper low-power shutdown may not take place. The
user can read back the power-status flag at page 0 / register 37, bit D7 and page 0 / register 37, bit D3.
When both of the flags indicate power-down, the MDAC divider may be powered down, followed by the
NDAC divider. Note that when the ADC clock dividers are powered down, the ADC clock is derived from
the DAC clocks.
The ADC modulator is clocked by ADC_MOD_CLK. For proper power-up of the ADC channel, these
clocks are enabled by the NADC and MADC clock dividers (page 0 / register 18, bit D7 = 1 and page 0 /
register 19, bit D7 = 1). When the ADC channel is powered down, the device internally initiates a powerdown sequence for proper shutdown. During this shutdown sequence, the NADC and MADC dividers must
not be powered down, or else a proper low-power shutdown may not take place. The user can read back
the power-status flag from page 0 / register 36, bit D6. When this flag indicates power down, the MADC
divider may be powered down, followed by NADC divider.
When ADC_CLK (ADC DSP clock) is derived from the NDAC divider output, the NDAC must be kept
powered up until the power-down status flags for ADC do not indicate power down. When the input to the
AOSR clock divider is derived from DAC_MOD_CLK, then MDAC must be powered up when ADC_fS is
needed (for example, when WCLK is generated by the TLV320AIC3120 device or AGC is enabled) and
can be powered down only after the ADC power-down flags indicate power-down status.
In general, for proper operation, all the root clock dividers must power down only after the child clock
dividers have powered down.
The TLV320AIC3120 device also has options for routing some of the internal clocks to the output pins of
the device to be used as general-purpose clocks in the system. The feature is shown in Figure 7-35.

In the mode when the TLV320AIC3120 device is configured to drive the BCLK pin (page 0 / register 27,
bit D3 = 1), the device is driven as the divided value of BDIV_CLKIN. The division value is programmed in
page 0 / register 30, bits D6–D0 from 1 to 128. The BDIV_CLKIN is configurable to be one of DAC_CLK
(DAC DSP clock), DAC_MOD_CLK, ADC_CLK (ADC DSP clock) or ADC_MOD_CLK by configuring the
BDIV_CLKIN multiplexer in page 0 / register 29, bits D1–D0. Additionally, a general-purpose clock can be
driven out on either GPIO1 or DOUT.
This clock can be a divided-down version of CDIV_CLKIN. The value of this clock divider can be
programmed from 1 to 128 by writing to page 0 / register 26, bits D6–D0. CDIV_CLKIN can also be

7.3.13.1 PLL
For lower power consumption, the best process is to derive the internal audio processing clocks using the
simple dividers. When the input MCLK or other source clock is not an integer multiple of the audio
processing clocks then using the on-board PLL is necessary. The TLV320AIC3120 fractional PLL
generates an internal master clock that produces the processing clocks required by the ADC, DAC, and
miniDSP. The programmability of this PLL allows operation from a wide variety of clocks that may be
available in the system.
The PLL input supports clocks varying from 512 kHz to 20 MHz and is register-programmable to enable
generation of the required sampling rates with fine resolution. The PLL turns on by writing to page 0 /
register 5, bit D7. When the PLL is enabled, the PLL output clock, PLL_CLK, is given by Equation 9.
PLL_CLKIN ´ R ´ J.D
PLL_CLK =

R = 1, 2, 3, ..., 16 (page 0 / register 5, default value = 1)

D = 0, 1, 2, …, 9999 (page 0 / register 7 and page 0 / register 8, default value = 0)
P = 1, 2, 3, …, 8 (page 0 / register 5, default value = 1)
(9)
The PLL turns on through page 0 / register 5, bit D7. The variable P is programmed through page 0 /
register 5, bits D6–D4. The variable R is programmed through page 0 / register 5, bits D3–D0. The
variable J is programmed through page 0 / register 6, bits D5–D0. The variable D is 14 bits and is
programmed into two registers. The MSB portion is programmed through page 0 / register 7, bits D5–D0,
and the LSB portion is programmed thrugh page 0 / register 8, bits D7–D0. For proper update of the Ddivider value, page 0 / register 7 must be programmed first, followed immediately by page 0 / register 8.
The new value of D does not take effect unless the write to page 0 / register 8 is complete.
When the PLL is enabled, the following conditions must be satisfied:

The PLL can power up independently from the ADC and DAC blocks, and can also be used as a generalpurpose PLL by routing the PLL output to the GPIO output. After powering up the PLL, PLL_CLK is
available typically after 10 ms.
The clocks for the codec and various signal processing blocks, CODEC_CLKIN, are generated from the
MCLK input, BCLK input, GPIO input, or PLL_CLK (page 0 / register 4, bits D1–D0).
If CODEC_CLKIN is derived from the PLL, then the PLL must be powered up first and powered down last.
Table 7-37 lists several example cases of typical PLL_CLKIN rates and how to program the PLL to
achieve a sample rate fS of either 44.1 kHz or 48 kHz.

7.3.14 Timer
The internal clock runs nominally at 8.2 MHz. This is used for various internal timing intervals, de-bounce
logic, and interrupts. The MCLK divider must be set in such a way that the divider output is approximately
1 MHz for the timers to be closer to the programmed value.

7.3.15 Digital Audio and Control Interface
7.3.15.1 Digital Audio Interface
Audio data is transferred between the host processor and the TLV320AIC3120 device through the digital
audio data, serial interface, or audio bus. The audio bus on this device is very flexible, including left- or
right-justified data options, support for I2S or PCM protocols, programmable data length options, a TDM
mode for multichannel operation, very flexible master and slave configurability for each bus-clock line, and
the ability to communicate with multiple devices within a system directly.
NOTE
The TLV320AIC3120 device has a mono DAC which inputs the mono data from the digital
audio data serial interface as the left channel, the right channel, or a mix of the left and right
channels as [(L + R) ÷ 2] (page 0 / register 63, bits D5–D4). The TLV320AIC3120 device has
a mono ADC which outputs the same data to both the left and right channels of the digital
audio data serial interface output. See for the signal flow of the DAC and ADC.
The audio bus of the TLV320AIC3120 device can be configured for left-justified or right-justified, I2S, DSP,
or TDM modes of operation, where communication with standard telephony PCM interfaces is supported
within the TDM mode. These modes are all MSB-first, with data width programmable as 16, 20, 24, or 32
bits by configuring page 0 / register 27, bits D5–D4. In addition, the word clock and bit clock can be
independently configured in either master or slave mode, for flexible connectivity to a wide variety of
processors. The word clock defines the beginning of a frame, and can be programmed as either a pulse or
a square-wave signal. The frequency of this clock corresponds to the maximum of the selected ADC and
DAC sampling frequencies.
The bit clock is used to clock-in and clock-out the digital audio data across the serial bus. When in master
mode, this signal can be programmed to generate variable clock pulses by controlling the bit-clock divider
in page 0 / register 30 (see Figure 7-33). The number of bit-clock pulses in a frame can require adjustment
to accommodate various word lengths as well as to support the case when multiple TLV320AIC3120s
share the same audio bus.
The TLV320AIC3120 device also includes a feature to offset the position of start-of-data transfer with
respect to the word clock. This offset is controlled in terms of number of bit-clocks and can be
programmed in page 0 / register 28.

SLAS653C – FEBRUARY 2010 – REVISED FEBRUARY 2017
The TLV320AIC3120 device also has the feature of inverting the polarity of the bit clock used for
transferring the audio data as compared to the default clock polarity used. This feature can be used
independently of the mode of audio interface chosen. This can be configured through page 0 / register 29,
bit D3.
The TLV320AIC3120 device further includes programmability (page 0 / register 27, bit D0) to place the
DOUT line in the high-impedance state during all bit clocks when valid data is not being sent. By
combining this capability with the ability to program at what bit clock in a frame the audio data begins,
time-division multiplexing (TDM) is accomplished, enabling the use of multiple codecs on a single audio
serial data bus. When the audio serial data bus is powered down while configured in master mode, the
pins associated with the interface are put into a high-impedance output condition.
By default, when the word clocks and bit clocks are generated by the TLV320AIC3120 device, these
clocks are active only when the codecs (ADC, DAC or both) are powered up within the device. This is
done to save power. However, it also supports a feature when both the word clocks and bit clocks can be
active even when the codec in the device is powered down. This is useful when using the TDM mode with
multiple codecs on the same bus, or when word clocks or bit clocks are used in the system as generalpurpose clocks.
7.3.15.1.1 Right-Justified Mode
The audio interface of the TLV320AIC3120 can enter the right-justified mode by programming page 0 /
register 27, bits D7–D6 = 10. In right-justified mode, the LSB of the left channel is valid on the rising edge
of the bit clock preceding the falling edge of the word clock. Similarly, the LSB of the right channel is valid
on the rising edge of the bit clock preceding the rising edge of the word clock.

For the right-justified mode, the number of bit clocks per frame should be greater-than or equal-to twice

The audio interface of the TLV320AIC3120 can enter the left-justified mode by programming page 0 /
register 27, bits D7–D6 = 11. In left-justified mode, the MSB of the right channel is valid on the rising edge
of the bit clock following the falling edge of the word clock. Similarly, the MSB of the left channel is valid
on the rising edge of the bit clock following the rising edge of the word clock.

For I2S mode, the number of bit clocks per channel should be greater-than or equal-to the programmed
word length of the data. Also, the programmed offset value should be less than the number of bit clocks
per frame by at least the programmed word length of the data.

7.3.15.1.4 DSP Mode
The audio interface of the TLV320AIC3120 can enter DSP mode by programming page 0 / register 27,
bits D7–D6 = 01. In DSP mode, the falling edge of the word clock starts the data transfer with the leftchannel data first and immediately followed by the right-channel data. Each data bit is valid on the falling
edge of the bit clock.

7.3.15.2 Primary and Secondary Digital Audio Interface Selection
The audio serial interface on the TLV320AIC3120 has extensive I/O control to allow communication with
two independent processors for audio data. The processors can communicate with the device one at a
time. This feature is enabled by register programming of the various pin selections. Table 7-38 shows the
primary and secondary audio interface selection and registers. Table 7-39 shows the selection criteria for
generating ADC_WCLK. Figure 7-48 is a high-level diagram showing the general signal flow and
multiplexing for the primary and secondary audio interfaces. For detailed information, see Table 7-38,
Table 7-39, and the register definitions in .

7.3.15.3 Control Interface
The TLV320AIC3120 control interface supports the I2C communication protocol.
7.3.15.3.1 I2C Control Mode
The TLV320AIC3120 supports the I2C control protocol, and responds to the I2C address of 0011 000. I2C
is a two-wire, open-drain interface supporting multiple devices and masters on a single bus. Devices on
the I2C bus only drive the bus lines LOW by connecting them to ground; they never drive the bus lines
HIGH. Instead, the bus wires are pulled HIGH by pullup resistors, so the bus wires are HIGH when no
device is driving them LOW. This way, two devices cannot conflict; if two devices drive the bus
simultaneously, there is no driver contention.
Communication on the I2C bus always takes place between two devices, one acting as the master and the
other acting as the slave. Both masters and slaves can read and write, but slaves can only do so under
the direction of the master. Some I2C devices can act as masters or slaves, but the TLV320AIC3120 can
only act as a slave device.
An I2C bus consists of two lines, SDA and SCL. SDA carries data, and the SCL signal provides the clock.
All data is transmitted across the I2C bus in groups of eight bits. To send a bit on the I2C bus, the SDA line
is driven to the appropriate level while SCL is LOW (a LOW on SDA indicates the bit is zero, while a HIGH
indicates the bit is one).
Once the SDA line has settled, the SCL line is brought HIGH, then LOW. This pulse on the SCL line
clocks the SDA bit into the receiver shift register.
The I2C bus is bidirectional: the SDA line is used both for transmitting and receiving data. When a master
reads from a slave, the slave drives the data line; when a master sends to a slave, the master drives the
data line.
Most of the time the bus is idle, no communication is taking place, and both lines are HIGH. When
communication is taking place, the bus is active. Only master devices can start communication on the bus.
Generally, the data line is only allowed to change state while the clock line is LOW. If the data line
changes state while the clock line is HIGH, it is either a START condition or the counterpart, a STOP
condition. A START condition is when the clock line is HIGH and the data line goes from HIGH to LOW. A
STOP condition is when the clock line is HIGH and the data line goes from LOW to HIGH.
After the master issues a START condition, it sends a byte that selects the slave device for
communication. This byte is called the address byte. Each device on an I2C bus has a unique 7-bit
address to which it responds. (Slaves can also have 10-bit addresses; see the I2C specification for
details.) The master sends an address in the address byte, together with a bit that indicates whether it is
to read from or write to the slave device.
Every byte transmitted on the I2C bus, whether it is address or data, is acknowledged with an
acknowledge bit. When a master has finished sending a byte (eight data bits) to a slave, it stops driving
SDA and waits for the slave to acknowledge the byte. The slave acknowledges the byte by pulling SDA
LOW. The master then sends a clock pulse to clock the acknowledge bit. Similarly, when a master has
finished reading a byte, it pulls SDA LOW to acknowledge this to the slave. It then sends a clock pulse to
clock the bit. (Remember that the master always drives the clock line.)
A not-acknowledge is performed by simply leaving SDA HIGH during an acknowledge cycle. If a device is
not present on the bus, and the master attempts to address the device, the master receives a notacknowledge because no device is present at that address to pull the line LOW.
When a master has finished communicating with a slave, it may issue a STOP condition. When a STOP
condition is issued, the bus becomes idle again. A master may also issue another START condition. When
a START condition is issued while the bus is active, it is called a repeated START condition.
The TLV320AIC3120 can also respond to and acknowledge a general call, which consists of the master
issuing a command with a slave address byte of 00h. This feature is disabled by default, but can be
enabled through page 0 / register 34, bit D5.

Figure 7-50. I2C Read
In the case of an I2C register write, if the master does not issue a STOP condition, then the device enters
auto-increment mode. So in the next eight clocks, the data on SDA is treated as data for the next
incremental register.
Similarly, in the case of an I2C register read, after the device has sent out the 8-bit data from the
addressed register, if the master issues a ACKNOWLEDGE, the slave takes over control of the SDA bus
and transmits for the next eight clocks the data of the next incremental register.

Register Map
TLV320AIC3120 Register Map
All features on this device are addressed using the I2C bus. All of the writable registers can be read back.
However, some registers contain status information or data, and are only available for reading.
The TLV320AIC3120 device contains several pages of 8-bit registers, and each page can contain up to
128 registers. The register pages are divided up based on functional blocks for this device. Page 0 is the
default home page after RESET. Page control occurs by writing a new page value into register 0 of the
current page.
The control registers for the TLV320AIC3120 device are described in detail as follows. All registers are 8
bits in width, with D7 referring to the most-significant bit of each register, and D0 referring to the leastsignificant bit.
Pages 0, 1, 3–5, 8–15, 32–43, and 64–95. All other pages and registers are reserved. Do not read from or
write to reserved pages and registers. Also, do not write other than the reset values for the reserved bits
and read-only bits of non-reserved registers; otherwise, device functionality failure can occur.
NOTE
Note that the page and register numbers are shown in decimal format. For use in microcode,
these decimal values may need to be converted to hexadecimal format. For convenience,
the register numbers are shown in both formats, whereas the page numbers are shown only
in decimal format.

The remaining page-4 registers are either reserved registers or are used for setting coefficients for the
various filters in the TLV320AIC3120. Reserved registers must not be written to.
The filter coefficient registers are arranged in pairs, with two adjacent 8-bit registers containing the 16-bit
coefficient for a single filter. The 16-bit integer contained in the MSB and LSB registers for a coefficient
are interpreted as a 2s-complement integer, with possible values ranging from –32 768 to 32 767. When
programming any coefficient value for a filter, the MSB register must always be written first, immediately
followed by the LSB register. Even if only the MSB or LSB portion of the coefficient changes, both
registers must be written in this sequence. is a list of the page-4 registers, excepting the previously
described register 0.

SLAS653C – FEBRUARY 2010 – REVISED FEBRUARY 2017
The remaining page-5 registers are either reserved registers or are used for setting coefficients for the
various filters in the TLV320AIC3120. Reserved registers must not be written to.
The filter coefficient registers are arranged in pairs, with two adjacent 8-bit registers containing the 16-bit
coefficient for a single filter. The 16-bit integer contained in the MSB and LSB registers for a coefficient
are interpreted as a 2s-complement integer, with possible values ranging from –32 768 to 32 767. When
programming any coefficient value for a filter, the MSB register must always be written first, immediately
followed by the LSB register. Even if only the MSB or LSB portion of the coefficient changes, both
registers must be written in this sequence. Table 7-163 is a list of the page-5 registers, excepting the
previously described register 0.

The remaining page-8 registers are either reserved registers or are used for setting coefficients for the
various filters in the TLV320AIC3120. Reserved registers must not be written to.
The filter coefficient registers are arranged in pairs, with two adjacent 8-bit registers containing the 16-bit
coefficient for a single filter. The 16-bit integer contained in the MSB and LSB registers for a coefficient
are interpreted as a 2s-complement integer, with possible values ranging from –32 768 to 32 767. When
programming any coefficient value for a filter, the MSB register must always be written first, immediately
followed by the LSB register. Even if only the MSB or LSB portion of the coefficient changes, both
registers must be written in this sequence. is a list of the page-8 registers, excepting the previously
described register 0.

The remaining page-9 registers are either reserved registers or are used for setting coefficients for the
various filters in the TLV320AIC3120. Reserved registers must not be written to.
The filter-coefficient registers are arranged in pairs, with two adjacent 8-bit registers containing the 16-bit
coefficient for a single filter. The 16-bit integer contained in the MSB and LSB registers for a coefficient
are interpreted as a 2s-complement integer, with possible values ranging from –32 768 to 32 767. When
programming any coefficient value for a filter, the MSB register must always be written first, immediately
followed by the LSB register. Even if only the MSB or LSB portion of the coefficient changes, both
registers must be written in this sequence. is a list of the page-9 registers, excepting the previously
described register 0.

The remaining page-10 registers are either reserved registers or are used for setting coefficients for the
various filters in the TLV320AIC3120. Reserved registers should not be written to.
The filter coefficient registers are arranged in pairs, with two adjacent 8-bit registers containing the 16-bit
coefficient for a single filter. The 16-bit integer contained in the MSB and LSB registers for a coefficient
are interpreted as a 2s-complement integer, with possible values ranging from –32 768 to 32 767. When
programming any coefficient value for a filter, the MSB register should always be written first, immediately
followed by the LSB register. Even if only the MSB or LSB portion of the coefficient changes, both
registers should be written in this sequence. Table 7-170 is a list of the page-10 registers, excepting the
previously described register 0.

The remaining page-12 registers are either reserved registers or are used for setting coefficients for the
various filters in the TLV320AIC3120. Reserved registers should not be written to.
The filter coefficient registers are arranged in pairs, with two adjacent 8-bit registers containing the 16-bit
coefficient for a single filter. The 16-bit integer contained in the MSB and LSB registers for a coefficient
are interpreted as a 2s-complement integer, with possible values ranging from –32 768 to 32 767. When
programming any coefficient value for a filter, the MSB register should always be written first, immediately
followed by the LSB register. Even if only the MSB or LSB portion of the coefficient changes, both
registers should be written in this sequence. is a list of the page-12 registers, excepting the previously
described register 0.

The remaining page-13 registers are either reserved registers or are used for setting coefficients for the
various filters in the TLV320AIC3120. Reserved registers must not be written to.
The filter coefficient registers are arranged in pairs, with two adjacent 8-bit registers containing the 16-bit
coefficient for a single filter. The 16-bit integer contained in the MSB and LSB registers for a coefficient
are interpreted as a 2s-complement integer, with possible values ranging from –32 768 to 32 767. When
programming any coefficient value for a filter, the MSB register must always be written first, immediately
followed by the LSB register. Even if only the MSB or LSB portion of the coefficient changes, both
registers must be written in this sequence. is a list of the page-13 registers, excepting the previously
described register 0.

The remaining page-14 registers are either reserved registers or are used for setting coefficients for the
various filters in the TLV320AIC3120. Reserved registers must not be written to.
The filter coefficient registers are arranged in pairs, with two adjacent 8-bit registers containing the 16-bit
coefficient for a single filter. The 16-bit integer contained in the MSB and LSB registers for a coefficient
are interpreted as a 2s-complement integer, with possible values ranging from –32 768 to 32 767. When
programming any coefficient value for a filter, the MSB register must always be written first, immediately
followed by the LSB register. Even if only the MSB or LSB portion of the coefficient changes, both
registers must be written in this sequence. Table 7-178 is a list of the page-14 registers, excepting the
previously described register 0.

The remaining page-15 registers are either reserved registers or are used for setting coefficients for the
various filters in the TLV320AIC3120. Reserved registers must not be written to.
The filter coefficient registers are arranged in pairs, with two adjacent 8-bit registers containing the 16-bit
coefficient for a single filter. The 16-bit integer contained in the MSB and LSB registers for a coefficient
are interpreted as a 2s-complement integer, with possible values ranging from –32 768 to 32 767. When
programming any coefficient value for a filter, the MSB register must always be written first, immediately
followed by the LSB register. Even if only the MSB or LSB portion of the coefficient changes, both
registers must be written in this sequence. Table 7-180 is a list of the page-15 registers, excepting the
previously described register 0.

Detailed Design Procedure
Using Figure 8-1 as a guide, integrate the hardware into the system.
Following the recommended component placement, schematic layout and routing given in Section 10,
integrate the device and its supporting components into the system PCB file.
Determining sample rate and master clock frequency is required since powering up the device as all
internal timing is derived from the master clock. Refer to Section 7.3.13 to get more information of how to
configure correctly the required clocks for the device.
As the TLV320AIC3120 is designed for low-power applications, when powered up, the device has several
features powered down. A correct routing of the TLV320AIC3120 signals is achieved by a correct setting
of the device registers, powering up the required stages of the device and configuring the internal switches
to follow a desired route. For more information of the device configuration and programming, refer to the
TLV320AIC3120's technical documents on ti.com.

9 Power Supply Recommendations
The TLV320AIC3120 has been designed to be extremely tolerant of power supply sequencing. However,
in some rare cases, unexpected conditions and behaviors can be attributed to power supply sequencing.
It is important to consider that the digital activity must be separated from the analog and speaker activity.
In order to separate the power supplies, the recommended power sequence is:
1. Speaker supplies
2. Digital supplies
3. Analog supplies
First, turn on the speaker supplies. Once they are stabilized, turn on the digital power supplies. Finally,
once the digital power supplies are stabilized, the analog power supplies must be turned on.
Also, TI recommends to add decoupling capacitors close to the power supplies pins (see Section 10 for
details). These capacitors will ensure that the power pins will be stable. Additionally, undesired effects
such pops will be avoided.

10 Layout
10.1 Layout Guidelines
PCB design is made considering the application and the review is specific for each system requirements.
However, general considerations can optimize the system performance.
• The TLV320AIC3120 thermal pad must be connected to analog output driver ground using multiple
VIAS to minimize impedance between the device and ground.
• Analog and digital grounds must be separated to prevent possible digital noise form affecting the
analog performance of the board.
• The TLV320AIC3120 requires the decoupling capacitors to be placed as close as possible to the
device power supply terminals.
