The SY24175D is a 2×20W, digital audio power amplifier for driving bridge-tied stereo speakers. One serial data input allows processing of up to two discrete audio channels and seamless integration to most digital audio processors. The SY24175D is an I²S slave device receiving all clocks from external sources.

The SY24175D has the essential audio signal processing functions like mixer, dynamic range control, loudness control, and parametric equalization.
