    AW8862CSR

    I2S/TDM Input, High Efficiency, 10.25V Boost, 3rd Generation Digital Smart K Audio Amplifier

    The AW8862 is an I2S/TDM input, high efficiency digital Smart K audio amplifier with an integrated 10.25V smart boost converter, sound quality enhancement algorithms and speaker protection. Due to its 11.5uV noise floor and ultra-low distortion, clean listening is guaranteed. It can delivers 5.4W (RMS, THD+N=1%) output power into an 8Ω speaker at a battery voltage of 4.2V. The AW8862 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 AW8862 features AWINIC proprietary AGC algorithm that prevents clipping noise and improves sound quality. The AW8862 supports speaker and receiver 2-in-1 applications. In the receiver application, it connects VDD directly to the Class-D amplifier power supply. The AW8862 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.
