说明
The AW8896 is an I2S input, high efficiency and 2nd AWINIC digital Smart K audio amplifier with an integrated adaptive boost converter, sound quality enhancement algorithms and speaker protection. Due to its 26μV noise floor and ultra-low distortion, clean listening is guaranteed. It can delivers 1.96W (RMS, THD+N = 1%) output power into a 8Ω speaker at a battery voltage of 4.2V.
The AW8896 features AWINIC new generation Feed-Forward Multi-Level AGC algorithm that prevents clipping noise and improves sound quality. The AW8896 also incorporates Bass and Treble enhancement function for increasing loudness and enhancing the quality of audio signal.
The AW8896 supports speaker and receiver 2-in-1 applications. In the receiver application, it connects VDD directly to the Class-D amplifier supply.
The AW8896 integrates a high-efficiency and adaptive boost converter as the Class-D amplifier supply rail. The boost converter output voltage is only raised when necessary. This improves the output dynamic range of audio signal while limiting quiescent power consumption.
The AW8896 features high RF suppression and eliminates TDD noise completely benefited from the audio input is I2S interface. General settings are communicated via an I2C-bus interface, and its I2C address is configurable.
The AW8896 offers Short Circuit Protection, Over-Temperature Protection, Under-Voltage Protection and Over-Voltage Protection to protect the device.
The AW8896 is available in a WLCSP 2.55mm×1.94mm-28B package with 400μm pitch.
