Description
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 26uV noise floor ａｎｄ ultra-low distortion, clean listening is guaranteed. It can delivers 2.62W (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. 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 400um pitch.
