Overview
The TAS5711PHP is a 20-W, efficient, digital audio power amplifier designed by Texas Instruments for driving stereo bridge-tied speakers. This device is optimized for high-performance audio applications, offering seamless integration with most digital audio processors and MPEG decoders. It features a single serial data input that can process up to two discrete audio channels, and it operates as an I2S slave-only device, receiving all clocks from external sources. The TAS5711PHP is known for its high efficiency, wide PVDD range, and advanced audio processing capabilities, including speaker equalization, dynamic range compression, and support for 2.1 and 2.0 audio modes.
