TAS5711PHPR
TAS5711PHPR - 20W Stereo Class-D Amplifier | Texas Instruments
The Texas Instruments TAS5711PHPR is a 20 W digital-input, open-loop Class-D audio power amplifier for stereo bridge-tied speakers, with 8 V to 26 V PVDD operation, 2.1-channel support, equalization, dynamic range control, and a 48-pin HTQFP package measuring 7 mm by 7 mm. Its digital signal path supports up to two discrete audio channels, while its integrated processing is designed for use with digital audio processors and MPEG decoders.
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.
