I2S Input, High Efficiency, Feed-Forward Multi-Level AGC 2nd Digital Smart K Audio Amplifier

The AW8896 is an I2S input, high efficiency and 2 nd AWINIC digital Smart K audio amplifier with an integrated adaptive boost converter, sound quality enhancement algorithms and speaker protection. Due to its 26uV noise floor and ultra-low distortion, clean listening is guaranteed. It can delivers 2.17W (RMS, THD+N=1%) output power into a 6Ω 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.
