Minimum spec applies if LDO is used. Minimum is 1.5V if LDO is not enabled. Using the LDO below 1.9V degrades LDO performance.
All grounds on board are tied together, so they should not differ in voltage by more than 0.2V max, for any combination of ground
signals.
At DVdd values lower than 1.65V, the PLL does not function. Please see table in SLAU434, Maximum TLV320DAC3203 Clock
Frequencies for details on maximum clock frequencies.

7 Detailed Description
7.1 Overview
Combined with the advanced PowerTune technology, the device can cover operations from 8kHz mono voice
playback to stereo 192kHz DAC playback, making it ideal for portable battery-powered audio and telephony
applications.
The playback path offers signal processing blocks for filtering and effects, true differential output signal, flexible
mixing of DAC and analog input signals as well as programmable volume controls. The TLV320DAC3203
contains two high-power output drivers which can be configured in multiple ways, including stereo and mono
BTL. The integrated PowerTune technology allows the device to be tuned to just the right power-performance
trade-off. Mobile applications frequently have multiple use cases requiring very low-power operation while being
used in a mobile environment. When used in a docked environment, power consumption typically is less of a
concern and lowest possible noise is more important. With PowerTune the TLV320DAC3203 can address both
cases.
The voltage supply range for the TLV320DAC3203 for analog is 1.5V–1.95V, and for digital it is 1.26V–1.95V. To
ease system-level design, a low-dropout regulator (LDO) is integrated to generate the appropriate analog supply
from input voltages ranging from 1.8V to 3.6V. Digital I/O voltages are supported in the range of 1.1V–3.6V.
The required internal clock of the TLV320DAC3203 can be derived from multiple sources, including the MCLK,
BCLK, GPIO pins or the output of internal PLL, where the input to the PLL again can be derived from the MCLK,
BCLK or GPIO pins. Although using the internal, fractional PLL ensures the availability of a suitable clock signal,
it is not recommended for the lowest power settings. The PLL is highly programmable and can accept available
input clocks in the range of 512kHz to 50MHz.

7.3 Feature Description
7.3.1 Device Connections
7.3.1.1 Digital Pins
Only a small number of digital pins are dedicated to a single function; whenever possible, the digital pins have a
default function, and also can be reprogrammed to cover alternative functions for various applications.
The fixed-function pins are Reset and the SPI_Select pin, which are HW control pins. Depending on the state of
SPI_Select, the two control-bus pins SCL/SS and SDA/MOSI are configured for either I2C or SPI protocol.
Other digital IO pins can be configured for various functions via register control. An overview of available
functionality is given in Multifunction Pins.
7.3.1.1.1 Multifunction Pins
Table 1 shows the possible allocation of pins for specific functions. The PLL input, for example, can be
programmed to be any of 4 pins (MCLK, BCLK, DIN, GPIO).

7.3.1.2 Analog Pins
Analog functions can also be configured to a large degree. For minimum power consumption, analog blocks are
powered down by default. The blocks can be powered up with fine granularity according to the application needs.
7.3.2 Analog Audio I/O
The analog I/O path of the TLV320DAC3203 offers a variety of options for signal conditioning and routing:
• 2 headphone amplifier outputs
• Analog gain setting
• Single ended and differential modes
7.3.2.1 Analog Low Power Bypass
The TLV320DAC3203 offers an analog-bypass mode. An analog signal can be routed from the analog input pin
to the output amplifier. Neither the digital-input processing blocks nor the DAC resources are required for such
operation; this supports low-power operation during analog-bypass mode.
In analog low-power bypass mode, line-level signals can be routed directly from the analog inputs INL to the left
headphone amplifier (HPL) and INR to HPR.
7.3.2.2 Headphone Outputs
The stereo headphone drivers on pins HPL and HPR can drive loads with impedances down to 16Ω in singleended AC-coupled headphone configurations, or loads down to 32Ω in differential mode, where a speaker is
connected between HPL and HPR. In single-ended drive configuration these drivers can drive up to 15mW
power into each headphone channel while operating from 1.8V analog supplies. While running from the AVdd
supply, the output common-mode of the headphone driver is set by the common-mode setting of analog inputs to
allow maximum utilization of the analog supply range while simultaneously providing a higher output-voltage
swing. In cases when higher output-voltage swing is required, the headphone amplifiers can run directly from the
higher supply voltage on LDOIN input (up to 3.6V). To use the higher supply voltage for higher output signal
swing, the output common-mode can be adjusted to either 1.25V, 1.5V or 1.65V. When the common-mode
voltage is configured at 1.65V and LDOIN supply is 3.3V, the headphones can each deliver up to 40mW power
into a 16Ω load.
The headphone drivers are capable of driving a mixed combination of DAC signal and bypass from analog input
INL and INR. The analog input signals can be attenuated up to 72dB before routing. The level of the DAC signal
can be controlled using the digital volume control of the DAC. To control the output-voltage swing of headphone
drivers, the digital volume control provides a range of –6.0dB to +29.0dB (1) in steps of 1dB. These level controls
are not meant to be used as dynamic volume control, but more to set output levels during initial device
configuration. Refer to for recommendations for using headphone volume control for achieving 0dB gain through
the DAC channel with various configurations.
7.3.3 Digital Microphone Inteface
The TLV320DAC3203 includes a stereo decimation filter for digital microphone inputs. The stereo recording path
can be powered up one channel at a time, to support the case where only mono record capability is required.
The digital microphone input path of the TLV320DAC3203 features a large set of options for signal conditioning
as well as signal routing:
• Stereo decimation filters (PDM input)
• Fine gain adjustment of digital channels with 0.1dB step size
• Digital volume control with a range of -12 to +20dB
• Mute function
In addition to the standard set of stereo decimation filter features the TLV320DAC3203 also offers the following
special functions:
• Channel-to-channel phase adjustment
• Adaptive filter mode
(1)
18
If the device must be placed into 'mute' from the –6.0dB setting, set the device at a gain of –5.0dB first, then place the device into mute.

7.3.3.1 ADC Processing Blocks — Overview
The TLV320DAC3203 includes a built-in digital decimation filter to process the oversampled data from the PDM
input to generate digital data at 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.
7.3.3.1.1
Processing Blocks
The TLV320DAC3203 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.
Table 2 gives an overview of the available processing blocks and their properties.
The signal processing blocks available are:
• First-order IIR
• Scalable number of biquad filters
• Variable-tap FIR filter
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. The Resource Class Column
(RC) gives an approximate indication of power consumption.

7.3.4 DAC
The TLV320DAC3203 includes a stereo audio DAC supporting data rates from 8kHz to 192kHz. Each channel of
the stereo audio DAC consists of a signal-processing engine with fixed processing blocks, a digital interpolation
filter, multi-bit 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 20kHz. To handle multiple input rates and optimize performance, the
TLV320DAC3203 allows the system designer to program the oversampling rates over a wide range from 1 to
1024. The system designer can choose higher oversampling ratios for lower input data rates and lower
oversampling ratios for higher input data rates.
The TLV320DAC3203 DAC channel includes a built-in digital interpolation filter to generate oversampled data for
the sigma-delta modulator. The interpolation filter can be chosen from three different types depending on
required frequency response, group delay and sampling rate.
The DAC path of the TLV320DAC3203 features many options for signal conditioning and signal routing:
• Digital volume control with a range of -63.5 to +24dB
• Mute function
• Dynamic range compression (DRC)
In addition to the standard set of DAC features the TLV320DAC3203 also offers the following special features:
• Built in sine wave generation (beep generator)
• Digital auto mute
• Adaptive filter mode
7.3.4.1 DAC Processing Blocks — Overview
The TLV320DAC3203 implements signal processing capabilities and interpolation filtering via processing blocks.
These fixed processing blocks give users the choice of how much and what type of signal processing they may
use and which interpolation filter is applied.
Table 3 gives an overview over all available processing blocks of the DAC channel and their properties.
The signal processing blocks available are:
• First-order IIR
• Scalable number of biquad filters
• 3D – Effect
• Beep Generator
The processing blocks are tuned for typical 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. The Resource Class Column (RC)
gives an approximate indication of power consumption.

7.3.5 Powertune
The TLV320DAC3203 features PowerTune, a mechanism to balance power-versus-performance trade-offs at the
time of device configuration. The 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.
For more detailed information see the TLV320DAC3203 Application Reference Guide.
7.3.6 Digital Audio I/O Interface
Audio data is transferred between the host processor and the TLV320DAC3203 via 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/slave configurability for each bus clock line, and the ability to communicate with multiple
devices within a system directly.
The audio bus of the TLV320DAC3203 can be configured for left or right-justified, I2S, DSP, or TDM modes of
operation, where communication with standard 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,
D(5:4). 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 is used to define the beginning of a
frame, and may be programmed as either a pulse or a square-wave signal. The frequency of this clock
corresponds to the DAC sampling frequency.
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. The number of bit-clock pulses in a frame may need adjustment to accommodate various wordlengths as well as to support the case when multiple TLV320DAC3203s may share the same audio bus.
The TLV320DAC3203 also includes a feature to offset the position of start of data transfer with respect to the
word-clock. This offset can be controlled in terms of number of bit-clocks and can be programmed in Page 0,
Register 28.
The TLV320DAC3203 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 via Page 0, Register 29, D(3).

TLV320DAC3203
SLOS756B – MAY 2012 – REVISED DECEMBER 2018
www.ti.com
The TLV320DAC3203 includes the programmability to program at what bit clock in a frame does audio data
begin. This enables time-division multiplexing (TDM), enabling use of multiple codecs on a single audio 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 hi-Z output condition.
By default when the word-clocks and bit-clocks are generated by the TLV320DAC3203, these clocks are active
only when the DAC is 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 DAC in the device is powered
down. This is useful when using the TDM mode with multiple codecs on the same bus, or when word-clock or bitclocks are used in the system as general-purpose clocks.
7.3.7 Clock Generation and PLL
The TLV320DAC3203 supports a wide range of options for generating clocks for the DAC as well as interface
and other control blocks. The clocks for the DAC require a source reference clock. This clock can be provided on
a variety of device pins such as MCLK, BCLK, or GPIO pins. The CODEC_CLKIN can then be routed through
highly-flexible clock dividers to generate the various clocks required for the DAC sections. In the event that the
desired audio clocks cannot be generated from the reference clocks on MCLK, BCLK, or GPIO, the
TLV320DAC3203 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 TLV320DAC3203
provides several programmable clock dividers to help achieve a variety of sampling rates for the DAC.
For more detailed information see the TLV320DAC3203 Application Reference Guide.
7.3.8 Control Interfaces
The TLV320DAC3203 control interface supports SPI or I2C communication protocols, with the protocol selectable
using the SPI_SELECT pin. For SPI, SPI_SELECT should be tied high; for I2C, SPI_SELECT should be tied low.
Changing the state of SPI_SELECT during device operation is not recommended.
7.3.8.1 I2C Control
The TLV320DAC3203 supports the I2C control protocol, and will respond to the I2C address of 0011000. 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 circuit prevents two devices from conflicting; if two devices drive the bus simultaneously, there is no driver
contention.
7.3.8.2 SPI Control
In the SPI control mode, the TLV320DAC3203 uses the pins SCL/SS as SS, SCLK as SCLK, MISO as MISO,
SDA/MOSI as MOSI; a standard SPI port with clock polarity setting of 0 (typical microprocessor SPI control bit
CPOL = 0). The SPI port allows full-duplex, synchronous, serial communication between a host processor (the
master) and peripheral devices (slaves). The SPI master (in this case, the host processor) generates the
synchronizing clock (driven onto SCLK) and initiates transmissions. The SPI slave devices (such as the
TLV320DAC3203) depend on a master to start and synchronize transmissions. A transmission begins when
initiated by an SPI master. The byte from the SPI master begins shifting in on the slave MOSI pin under the
control of the master serial clock (driven onto SCLK). As the byte shifts in on the MOSI pin, a byte shifts out on
the MISO pin to the master shift register.
For more detailed information see the TLV320DAC3203 Application Reference Guide.
7.4 Device Functional Modes
The following special functions are available to support advanced system requirements:
• Headset detection
• Interrupt generation
• Flexible pin multiplexing

8.2.2 Detailed Design Procedure
In this application, the device is able to use both digital and analog inputs, routing this signal into the headphone
outputs.
The internal LDO is being used in this application. External 1.8-V supply is used to power LDOIN, DVDD and
IOVDD. AVDD is internally supplied by the LDO.
Decoupling capacitors should be used at all the supply lines. TI recommends using 0.1-µF and 10-µF capacitors
for a better system performance.
Decoupling series capacitors must be used at the analog input and headphone output. The headphone output
can be connected in single-ended mode with DC offset voltage while the decoupling series capacitor protects the
speaker form the DC voltage. In addition the headphone output can be connected in a mono differential mode.
All grounds are tied together; route analog and digital paths are separated to avoid interference.

10 Layout
10.1 Layout Guidelines
If the analog inputs are:
• Used, analog input traces must be routed symmetrically for true differential performance.
• Used, do not run analog input traces parallel to digital lines.
• Used, they must be AC-coupled.
• Not used, they must be grounded through a capacitor.
Use a ground plane with multiple vias for each terminal to create a low-impedance connection to GND for
minimum ground noise.
Use supply decoupling capacitors and place them as close as possible to the device.
