TAS5825M - 4.5V to 26V, 38-W Stereo, Digital Input, Class-D Audio Amp with 96-kHz/192-kHz flexible Processing

The TAS5825M is a stereo high-performance closed-loop Class-D with integrated audioprocessor with up to 192-kHz architecture.

The powerful audio DSP core supports several advanced audio process flows. With 48-kHz or96-kHz architecture, an integrated SRC (Sample rate convertor) detects the input sample ratechange. Then auto converts to the target sample rate which DSP is running to avoid any audioartifacts. These process flows support: 2×15 BQs, 3-Band DRC, Full-band AGL (Automatic GainLimiter), Smart Amplifier Algorithm (Thermal and Excursion Protection), Bass enhancement,Spatializer,THD manager, PVDD Tracking and Thermal Foldback. The 192-kHz process flow offersFull-band AGL and Thermal Foldback .
