The DRV5825P is a stereo high-performance closed-loop Class-D with integrated audio processor with up to 96-kHz architecture.

The powerful audio DSP core supports advanced audio processing. 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 flow supports: 2×15 BQs, Adaptive I/V Limiter based on Piezo speaker impedance and LC filter model, Full-band AGL (Automatic Gain Limiter),THD manager (Clipper).
