The SY6045C 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. SY6045C is an I2S slave device receiving all clocks from external sources.

The SY6045C has a mixer and Bi-Quad filters which can be used to accomplish essential audio signal processing functions like dynamic range control, loudness control, and parametric equalization.
