The AW85805S is a high-efficiency, stereo digital class D audio amplifier with low power dissipation and sound enrichment. The device employs a multiple switching frequency option and Spread Spectrum technology to enhance EMI performance, avoid AM/FM interferences. And it supports Multichip synchronization and channel phase shift. The AW85805S integrates SKTune algorithm that includes parametric audio path equalizer, dynamic range control, etc. The SKTune algorithm maximizes speaker performance while maintaining safe working conditions. AW85805S supports Over-Current Protection, Over-Temperature Protection, DC Protection, Under-Voltage/Over-Voltage Protection, short-circuit Protection to protect the device. AW85805S is available in a ETSSOP-28L Package.
