The AW88166 is an I2S/TDM input, high efficiency digital Smart K audio amplifier with an integrated 6.25V smart boost converter, sound quality enhancement algorithm ａｎｄ speaker protection. Due to its 10μV noise floor ａｎｄ ultra-low distortion, clean listening is guaranteed. It can deliver 2.1W output power into an 8Ω speaker at 1% THD+N.
The AW88166 integrates SKTune algorithm that include parametric audio path equalizer, dynamic range control, anti-clip voltage limiter ａｎｄ speaker protection. The SKTune algorithm maximizes speaker performance while maintaining safe speaker conditions.
The AW88166 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 AW88166 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 AW88166 offers Short Circuit Protection, Over-Temperature Protection, Under-Voltage Protection ａｎｄ Over-Voltage Protection to protect the device.
AW88166 is available ｉｎ a FCQFN Package, body size is 2.0mmX2.5mmX0.55mm-22L.
