Description

The AW88103 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 10V 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 AW88103 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 AW88103 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 AW88103 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 AW88103 offers Short Circuit Protection, Over-Temperature Protection, Under-Voltage Protection and Over-Voltage Protection to protect the device. AW88103 is available in a WLCSP 1.77X2.175-20B(0.55) Package.
