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

The powerful audio DSP core supports several advanced audio process flows. With 48-kHz or 96-kHz architecture, an integrated SRC (Sample rate convertor) detects the input sample rate change. Then auto converts to the target sample rate which DSP is running to avoid any audio artifacts. These process flows support: 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 192-kHz process flow offers Full-band AGL and Thermal Foldback .
