Texas Instruments
The TAS5825M is a high-performance, stereo closed-loop Class-D with integrated auido processor with up to 192-kHz architecture.
The powerful DSP audio processing core support several advanced audio process flows. Even with 192-kHz architecture, TAS5825M provide a rich processing, such as 2×12 BQs, volume control, audio mixer, 2 Band DRC and a Full Band AGL. With 48-kHz or 96-kHz architecture, an integrated SRC (Sample rate convertor) detects the input sample rate change and auto convert to the target sample rate which DSP is running to avoid any audio artifacts, these process flows support richer processing, such as 2×15 BQs, 3-Band DRC, Full-band AGL (Automatic Gain Limiter), Smart Amplifier Algorithm (Speaker Thermal/Excursion Protection), Bass enhancement, Spatializer, THD manager and so on.
