TAS5711PHPR Overview
A Class-D audio amplifier is a switching power amplifier that uses efficient transistor output stages to drive speakers through LC filter networks. It belongs to the broader class of audio amplifiers, power amplifiers, and analog and mixed-signal semiconductors. Compared with a linear amplifier, the TAS5711 family is intended to reduce power dissipation while delivering high output power for portable consumer-audio equipment, soundbars, compact televisions, and other embedded audio systems.
The verified manufacturer data identifies the TAS5711 as a 20 W stereo amplifier operating from an 8 V to 26 V supply and reaching up to 90% efficiency. It provides digital audio input, programmable channel routing, AD and BD filter-mode support, EQ, DRC, and 2.1 mode. The verified datasheet search result also lists SNR of 106 dB, A-weighted, and describes bridge-tied-load operation for stereo speakers.
The device accepts a wide range of input data and data rates through its serial digital interface. This makes the signal path suitable for systems where audio is already processed by a digital audio codec, decoder, application processor, or MPEG source. The internal programmable path can route two discrete channels and supports audio processing functions without requiring a separate analog preamplifier for those functions.
Typical uses include stereo speaker drive, compact 2.1 speaker systems, consumer-audio equipment, soundbar amplification, and embedded audio products requiring efficient digital power amplification. The supplied PVDD range provides design flexibility for battery-powered and external-amplifier architectures, although actual speaker output depends on supply voltage, load impedance, thermal conditions, and filter design.
Designers should follow the manufacturer datasheet for the exact pin functions, exposed-pad connection, LC filter values, thermal layout, digital interface timing, and power-supply decoupling. Because the part is a Class-D output stage, speaker outputs require the specified external filtering network. PCB placement should keep the power-loop area small, provide adequate copper for thermal dissipation, and route sensitive digital signals away from output switching nodes.
This product record consolidates the verified manufacturer description, distributor identification, package information, and practical replacement-search results. It is intended to support design review, sourcing, and datasheet discovery; verify the current datasheet and part-status notices before committing a production design.

Typical Applications
TAS5711PHPR is suitable for 6 applications: Stereo Speaker Amplification, 2.1 Speaker Systems, Compact Soundbar Audio, MPEG Decoder Speaker Output, Embedded Consumer Audio, Battery-Powered Portable Audio.
Stereo Speaker Amplification
The TAS5711PHPR suits stereo speaker designs requiring 20 W of digital Class-D output from an 8 V to 26 V PVDD supply. Its serial digital input can receive processed channels from a codec, MPEG decoder, or application processor, while the programmable data path routes audio to the bridge-tied outputs. Designers should use the manufacturer-specified LC speaker filters and verify thermal performance for the selected 8-ohm load and ambient conditions. The advantage over a generic analog amplifier is integrated digital processing and efficient Class-D operation; the trade-off is the need to design the digital interface and filter network correctly.
Recommended
2.1 Speaker Systems
The verified manufacturer description specifically identifies 2.1 support, making TAS5711PHPR appropriate for compact systems that combine stereo channels with a subwoofer output. Its digital processing path can accept multiple discrete channels and use EQ and DRC before the power stage. The system designer must confirm the exact channel-routing configuration and external filter requirements in the current TI datasheet. Compared with a discrete analog power stage, this device reduces design complexity when the source is digital, but firmware and channel mapping become part of the critical design scope.
Recommended
Compact Soundbar Audio
A soundbar can use the TAS5711PHPR to convert digital audio streams into efficient bridge-tied Class-D speaker drive. The 20-W rating, 8 V to 26 V PVDD range, and up-to-90% efficiency make the part suitable for space-constrained consumer audio products, subject to thermal and load validation. Digital EQ and DRC can be applied through the programmable path without an analog preamp for those functions. Layout must preserve low-noise digital routing while keeping the Class-D switching loops and speaker filters controlled for EMI.
Recommended
MPEG Decoder Speaker Output
TAS5711PHPR fits systems where an MPEG decoder supplies serial digital audio and requires direct speaker amplification. The manufacturer describes one serial data input supporting up to two discrete channels and integration with MPEG decoders, which simplifies the signal chain compared with adding a separate analog-input amplifier. The design must still validate digital timing, sample-rate support, channel routing, and the required output filters against the TI documentation. The principal trade-off is dependence on correct digital configuration rather than simple analog volume control.
Recommended
Embedded Consumer Audio
The TAS5711PHPR can serve as the power-amplifier stage in compact consumer products where efficiency, digital processing, and board area are priorities. Its Class-D architecture supports up to 90% efficiency in the verified manufacturer description, helping reduce heat relative to a less efficient linear stage in suitable load conditions. The device is not automatically a complete audio system: supply regulation, speaker filters, EMI control, thermal copper, and digital source integration remain required. Prototype measurements should confirm output power, distortion, thermal rise, and EMI margin.
Recommended
Battery-Powered Portable Audio
The 8 V minimum PVDD and 26 V maximum PVDD range can support battery-derived or boosted supplies in portable audio products, provided the supply stays within the manufacturer limits. The device's digital input is useful when the audio source is a codec or embedded processor, and its efficiency helps reduce power consumption in the amplification stage. Designers should not interpret the 20-W rating as a guarantee at every impedance or supply condition; test the actual speaker load, battery range, thermal environment, and LC filter implementation.

Design Notes
Place the TAS5711PHPR power-supply decoupling components and the exposed-pad thermal connection according to the current TI layout guidance. Keep the high-current switching loop compact and provide a low-impedance return from the power stage. The 48-pin HTQFP package has a 7 mm by 7 mm body, so adequate copper and via placement are important for heat spreading and stable supply behavior.
Route the Class-D speaker outputs only through the manufacturer-specified filter network and keep the switching nodes compact. Digital audio traces should remain away from output-filter components and switching-current paths. Validate radiated and conducted emissions on the finished PCB because the verified 20 W Class-D capability and up-to-90% efficiency do not determine EMI performance without the actual layout, load, cables, and enclosure.
Do not substitute a related 25 W Class-D amplifier solely because its headline output rating is higher. The supplied search data does not verify the package, pinout, serial interface, filter modes, or control logic for TAS5715PHP, TAS5727PHPR, or TAS5631BPHDR. Confirm the complete TI pin table, absolute maximum ratings, thermal pad connection, external filter values, and digital timing before considering any replacement.
Treat the 8 V to 26 V PVDD range and 20 W rating as design inputs, not universal output guarantees. Verify the supply transient margin, speaker impedance, channel configuration, filter losses, ambient temperature, and allowed output distortion in the target application. The verified efficiency figure of up to 90% should be measured under the intended load and supply conditions rather than used as a fixed design assumption.
Compliance Information
The supplied verified product snippets identify the manufacturer, package, device function, power rating, supply range, and related search results but do not explicitly state environmental or automotive compliance. Confirm current TI compliance documentation before production release.
