The TAS5825M is a stereo high-performance closed-loop Class-D with an integrated audio processor and up to 192-kHz support.

The powerful audio DSP core supports several advanced audio process flows such as 2×15 BQs, 3-Band DRC, Full-band AGL (Automatic Gain Limiter), Smart Amplifier Algorithm (Thermal and Excursion Protection), Bass enhancement, Spatializer, THD manager, PVDD Tracking, and Thermal Foldback. The TAS5825M has a 48-kHz or 96-kHz architecture with an integrated SRC (Sample Rate Convertor) that detects the input sample rate and auto-converts the input sample to the DSP target sample rate to avoid audio artifacts.
