Description

The AW88397 is an I2S/TDM input, high efficiency digital Smart K audio amplifier with an integrated 10.25V smart boost converter. Due to its 8μV noise floor and ultra-low distortion, clean listening is guaranteed. It can deliver 5.4W output power into an 8Ω speaker at 1% THD+N. The AW88397 integrates SKTune algorithm that includes parametric audio path equalizer, multi-band dynamic range control, anti-clip voltage limiter and speaker protection. The SKTune algorithm maximizes speaker performance while maintaining safe speaker conditions. The AW88397 integrates a high-efficiency smart boost converter as the Class-D amplifier supply rail. The output voltage of boost converter can be adjusted smartly according to the input amplitude, which extremely improves the efficiency without clipping distortion. The AW88397 features high RF suppression and eliminates TDD noise completely benefited from the digital audio input interface. General settings are communicated via an I2C-bus interface, and the device address is configurable. The AW88397 offers Short Circuit Protection, Over-Temperature Protection, Under-Voltage Protection and Over-Voltage Protection to protect the device. AW88397 is available in a  FOWLP 2.75mmX3.25mmX0.543mm-42B package.
