The SY24145S is a 2×30W, 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 SY24145S is an I²S slave device receiving all clocks from the external sources.

The SY24145S has the essential audio signal processing functions like dynamic range control, loudness control and parametric equalization.
