The SY24146S 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 SY24146S is an I2S slave device receiving all clocks from the external sources.
The SY24146S has the essential audio signal processing functions like dynamic range control, loudness control and parametric equalization.
