Product Overview
The TAS5716 is a high-performance 20-W stereo digital-input Class-D audio amplifier from Texas Instruments, featuring integrated speaker equalization, dynamic range control (DRC), bass boost, and 3D sound enhancement. Part of TI’s PurePath digital audio family, it accepts two serial audio input ports supporting up to four channels and offers flexible output configurations including stereo bridged (20 W x 2), four-channel single-ended (10 W x 4), and 2.1-channel (stereo + subwoofer) modes. The closed-loop power stage architecture provides improved power supply rejection and higher damping factor for superior audio quality. With support for 32 kHz to 192 kHz sample rates and 0.05% THD+N performance, the TAS5716 is ideal for flat-panel TVs, soundbars, PC speakers, and home audio systems requiring high efficiency with rich audio processing.
