3 Description
The TPA2005D1-Q1 device is a 1.4-W high-efficiency
filter-free class-D audio power amplifier in a SON or
MSOP-PowerPAD package that requires only three
external components.
Features like 84% efficiency, –71-dB PSRR at
217 Hz, improved RF-rectification immunity, and 15mm2 total PCB area make TPA2005D1-Q1 ideal for
low-power audio applications in infotainment and
cluster.
The device allows for independent gain control by
summing the signals from each function while
minimizing noise to only 48 µVRMS. Additionally, the
TPA2005D1-Q1 device offers fast start-up time of 9
ms with minimal pop and has short circuit and
thermal protection.

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended
Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
For the MSOP (DGN) package option, the maximum VDD should be limited to 5 V if short-circuit protection is desired.

9 Detailed Description
9.1 Overview
The TPA2005D1-Q1 device is a high-efficiency filter-free Class-D audio amplifier capable of delivering up to 1.4
W into 8-Ω loads with a 5-V power supply. The fully-differential design of this amplifier avoids the usage of
bypass capacitors and the improved CMRR eliminates the usage of input-coupling capacitors. This makes the
device size a perfect choice for small, space constrained applications as only three external components are
required. The advanced modulation used in the TPA2005D1-Q1 PWM output stage eliminates the need for an
output filter.

9.3 Feature Description
9.3.1 Fully Differential Amplifier
The TPA2005D1-Q1 device is a fully differential amplifier with differential inputs and outputs. The fully differential
amplifier consists of a differential amplifier and a common-mode amplifier. The differential amplifier ensures that
the amplifier outputs a differential voltage on the output that is equal to the differential input times the gain. The
common-mode feedback ensures that the common-mode voltage at the output is biased around VDD / 2,
regardless of the common-mode voltage at the input. The fully differential TPA2005D1-Q1 device can still be
used with a single-ended input; however, the TPA2005D1-Q1 device should be used with differential inputs when
in a noisy environment to ensure maximum noise rejection.
9.3.1.1 Advantages Of Fully Differential Amplifiers
Fully differential amplifiers have the following advantages:
• Input-coupling capacitors not required:
– The fully differential amplifier allows the inputs to be biased at a voltage other than mid-supply. For
example, if a codec has a mid-supply lower than the mid-supply of the TPA2005D1-Q1 device, the
common-mode feedback circuit adjusts, and the TPA2005D1-Q1 outputs still is biased at mid-supply of
the TPA2005D1-Q1 device. The inputs of the TPA2005D1-Q1 device can be biased from 0.5 V to VDD –
0.8 V. If the inputs are biased outside of that range, input-coupling capacitors are required.
• Mid-supply bypass capacitor, C(BYPASS), not required:
– The fully differential amplifier does not require a bypass capacitor. This is because any shift in the midsupply affects both positive and negative channels equally and cancels at the differential output.

Feature Description (continued)
•
Better RF immunity:
– The fully differential amplifier cancels noise from RF interference much better than the typical audio
amplifier.
9.3.2 Efficiency and Thermal Information
As an example, the DRB package has a RθJA of 49.5°C/W, the maximum allowable junction temperature of
150°C, and a maximum internal dissipation of 0.2 W (worst case 5-V supply and 8-Ω load). Use Equation 1 to
calculate the maximum ambient temperature.
TAMax = TJMax – RθJAPDmax = 150 – 49.5(0.2) = 140.1°C
(1)
Equation 1 shows that the calculated maximum ambient temperature is 140.1°C at maximum power dissipation
with a 5-V supply; however, the maximum ambient temperature of the package is limited to 85°C (note that the
TPA2005D1TDGNRQ1 supports up to 105°C). Because of the efficiency of the TPA2005D1-Q1, it can operate
under all conditions to an ambient temperature of 85°C. The TPA2005D1-Q1 is designed with thermal protection
that turns the device off when the junction temperature surpasses 150°C to prevent damage to the IC. Also,
using speakers more resistive than 8 Ω dramatically increases the thermal performance by reducing the output
current and increasing the efficiency of the amplifier.
9.3.3 Eliminating the Output Filter With the TPA2005D1-Q1
This section focuses on why the user can eliminate the output filter with the TPA2005D1-Q1.
9.3.3.1 Effect On Audio
The class-D amplifier outputs a pulse-width modulated (PWM) square wave, which is the sum of the switching
waveform and the amplified input audio signal. The human ear acts as a band-pass filter such that only the
frequencies between approximately 20 Hz and 20 kHz are passed. The switching frequency components are
much greater than 20 kHz, so the only signal heard is the amplified input audio signal.
9.3.3.2 Traditional Class-D Modulation Scheme
The traditional class-D modulation scheme has a differential output in which each output is 180 degrees out of
phase and changes from ground to the supply voltage, VDD. Therefore, the differential pre-filtered output varies
between positive and negative VDD, where filtered 50% duty cycle yields 0 V across the load. The traditional
class-D modulation scheme with voltage and current waveforms is shown in Figure 31. Note that, even at an
average of 0 V across the load (50% duty cycle), the current to the load is high, causing a high loss and thus
causing a high supply current.

9.3.3.3 TPA2005D1-Q1 Modulation Scheme
The TPA2005D1-Q1 device uses a modulation scheme that still has each output switching from 0 to the supply
voltage. However, OUT+ and OUT– are now in phase with each other, with no input. The duty cycle of OUT+ is
greater than 50% and OUT– is less than 50% for positive voltages. The duty cycle of OUT+ is less than 50% and
OUT– is greater than 50% for negative voltages. The voltage across the load remains at 0 V throughout most of
the switching period, greatly reducing the switching current, which reduces any I2R losses in the load.

9.3.3.4 Efficiency: Why You Must Use a Filter With The Traditional Class-D Modulation Scheme
The main reason that the traditional class-D amplifier needs an output filter is that the switching waveform results
in maximum current flow. This causes more loss in the load, which causes lower efficiency. The ripple current is
large for the traditional modulation scheme because the ripple current is proportional to voltage multiplied by the
time at that voltage. The differential voltage swing is 2 × VDD, and the time at each voltage is one-half the period
for the traditional modulation scheme. An ideal LC filter is needed to store the ripple current from each half-cycle
for the next half-cycle, while any resistance causes power dissipation. The speaker is both resistive and reactive,
whereas an LC filter is almost purely reactive.
The TPA2005D1-Q1 modulation scheme has very little loss in the load without a filter because the pulses are
very short and the change in voltage is VDD instead of 2 × VDD. As the output power increases, the pulses widen,
making the ripple current larger. Ripple current could be filtered with an LC filter for increased efficiency, but for
most applications the filter is not needed.
An LC filter with a cutoff frequency less than the class-D switching frequency allows the switching current to flow
through the filter instead of the load. The filter has less resistance than the speaker, resulting in less power
dissipation, which increases efficiency.

9.3.3.5 Effects Of Applying a Square Wave Into a Speaker
If the amplitude of a square wave is high enough and the frequency of the square wave is within the bandwidth
of the speaker, a square wave could cause the voice coil to jump out of the air gap, scar the voice coil, or both. A
250-kHz switching frequency, however, is not significant because the speaker cone movement is proportional to
1/f2 for frequencies beyond the audio band. Therefore, the amount of cone movement at the switching frequency
is very small. However, damage could occur to the speaker if the voice coil is not designed to handle the
additional power. To size the speaker for added power, the ripple current dissipated in the load must be
calculated by subtracting the theoretical supplied power, PSUP THEORETICAL, from the actual supply power, PSUP, at
maximum output power, POUT. The switching power dissipated in the speaker is the inverse of the measured
efficiency, ηMEASURED, minus the theoretical efficiency, ηTHEORETICAL.

The maximum efficiency of the TPA2005D1-Q1 device with a 3.6-V supply and an 8-Ω load is 86% from
Equation 5. Using Equation 4 with the efficiency at maximum power (84%). An additional 17 mW is dissipated in
the speaker. The added power dissipated in the speaker is not an issue as long as it is taken into account when
choosing the speaker.
9.3.3.6 When to Use an Output Filter
Design the TPA2005D1-Q1 device without an output filter if the traces from amplifier to speaker are short. The
TPA2005D1-Q1device passed FCC and CE radiated emissions with no shielding and with speaker trace wires
100 mm long or less.
A ferrite bead filter often can be used if the design is failing radiated emissions without an LC filter, and the
frequency-sensitive circuit is greater than 1 MHz. If choosing a ferrite bead, choose one with high impedance at
high frequencies, but very low impedance at low frequencies.
Use an LC output filter if there are low-frequency (

TPA2005D1-Q1 device with differential inputs and input capacitors, and Figure 41 shows the TPA2005D1-Q1

CI is needed only for single-ended input or if VICM is not between 0.5 V and VDD – 0.8 V. CI = 3.3 nF (with RI = 150 kΩ) gives a highpass corner frequency of 321 Hz.
10.2.1.2.2 Input Resistors (RI)
The input resistors (RI) set the gain of the amplifier according to equation Equation 19.

Gain = 2 ´

(19)
Resistor matching is very important in fully differential amplifiers. The balance of the output on the
reference voltage depends on matched ratios of the resistors. CMRR, PSRR, and cancellation of the second
harmonic distortion diminish if resistor mismatch occurs. Therefore, it is recommended to use 1% tolerance
resistors, or better, to keep the performance optimized. Matching is more important than overall tolerance.
Resistor arrays with 1% matching can be used with a tolerance greater than 1%.
Place the input resistors very close to the TPA2005D1-Q1 to limit noise injection on the high-impedance nodes.
For optimal performance, the gain should be set to 2 V/V or lower. Lower gain allows the TPA2005D1-Q1 to
operate at its best and keeps a high voltage at the input, making the inputs less susceptible to noise.
10.2.1.2.3 Decoupling Capacitor (CS)
The TPA2005D1-Q1 is a high-performance class-D audio amplifier that requires adequate power-supply
decoupling to ensure the efficiency is high and total harmonic distortion (THD) is low. For higher frequency
transients, spikes, or digital hash on the line, a good low equivalent-series-resistance (ESR) ceramic capacitor,
typically 1 μF, placed as close as possible to the device VDD lead, works best. Placing this decoupling capacitor
close to the TPA2005D1-Q1 is very important for the efficiency of the class-D amplifier, because any resistance
or inductance in the trace between the device and the capacitor can cause a loss in efficiency. For filtering lowerfrequency noise signals, a 10-μF, or greater, capacitor placed near the audio power amplifier also helps, but it is
not required in most applications because of the high PSRR of this device.

10.2.2.1 Detailed Design Requirements
10.2.2.1.1 Input Capacitors (CI)
The TPA2005D1-Q1device does not require input coupling capacitors if the design uses a differential source that
is biased from 0.5 V to VDD – 0.8 V (shown in Figure 38). If the input signal is not biased within the
recommended common-mode input range, if needing to use the input as a high pass filter (shown in Figure 40),
or if using a single-ended source (shown in Figure 41), input coupling capacitors are required.
The input capacitors and input resistors form a high-pass filter with the corner frequency, fc, determined in
Equation 20.

fC =
(2p RI CI )
(20)
The value of the input capacitor is important to consider, as it directly affects the bass (low frequency)
performance of the circuit.
Equation 21 is reconfigured to solve for the input coupling capacitance.

If the corner frequency is within the audio band, the capacitors should have a tolerance of ±10% or better,
because any mismatch in capacitance causes an impedance mismatch at frequencies lower than the corner
frequency.
For a flat low-frequency response, use large input coupling capacitors (1 μF).

11 Power Supply Recommendations
The TPA2005D1-Q1 device is designed to operate from an input voltage supply range between 2.5-V and 5.5-V.
Therefore, the output voltage range of power supply should be within this range and well regulated. The current
capability of upper power should not exceed the maximum current limit of the power switch.
11.1 Power Supply Decoupling Capacitors
The TPA2005D1-Q1 device requires adequate power supply decoupling to ensure a high efficiency operation
with low total harmonic distortion (THD). Place a low equivalent-series-resistance (ESR) ceramic capacitor,
typically 0.1 µF, within 2 mm of the VDD pin. This choice of capacitor and placement helps with higher frequency
transients, spikes, or digital hash on the line. In addition to the 0.1 μF ceramic capacitor, TI recommends to place
a 2.2-µF to 10-µF capacitor on the VDD supply trace. This larger capacitor acts as a charge reservoir, providing
energy faster than the board supply, thus helping to prevent any droop in the supply voltage.

12 Layout
12.1 Layout Guidelines
12.1.1 Component Location
Place all the external components very close to the TPA2005D1-Q1 device. The input resistors need to be very
close to the TPA2005D1-Q1 input pins so noise does not couple on the high-impedance nodes between the
input resistors and the input amplifier of the TPA2005D1-Q1 device. Placing the decoupling capacitor, CS, close
to the TPA2005D1-Q1 device is important for the efficiency of the class-D amplifier. Any resistance or inductance
in the trace between the device and the capacitor can cause a loss in efficiency.
12.1.2 Trace Width
Make the high current traces going to pins VDD, GND, VO+ and VO– of the TPA2005D1-Q1 device have a
minimum width of 0.7 mm. If these traces are too thin, the TPA2005D1-Q1 performance and output power will
decrease. The input traces do not need to be wide, but do need to run side-by-side to enable common-mode
noise cancellation.
12.1.3 8-Pin QFN (DRB) Layout
Use the following land pattern for board layout with the 8-pin QFN (DRB) package. Note that the solder paste
should use a hatch pattern to fill solder paste at 50% to ensure that there is not too much solder paste under the
package.
