Description

The AW85806 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 AW85806 integrates SKTune algorithm that includes parametric audio path equalizer, dynamic range control, anti-clip voltage limiter and smart protection, etc. The SKTune algorithm maximizes speaker performance while maintaining safe working conditions. The AW85806 supports Over-Current Protection, Over-Temperature Protection, DC Protection, Under-Voltage/Over-Voltage Protection, short-circuit Protection to protect the device. AW85806 is available in a ETSSOP-28L Package.
