说明
The AW8838 is an I2S input, high efficiency digital Smart K audio amplifier with an integrated 6V adaptive charge pump, sound quality enhancement algorithms and speaker protection. Due to its 15μV noise floor and ultra-low distortion, clean listening is guaranteed. It can delivers 1.8W (RMS, THD+N = 1%) output power into an 8Ω speaker at a battery voltage of 4.2V.
The AW8838 integrates a high-efficiency adaptive charge pump as the Class-D amplifier supply rail. The output voltage of charge pump is only raised when necessary. This improves the output dynamic range of audio signal while limiting quiescent power consumption.
The AW8838 features AWINIC proprietary AGC algorithm that prevents clipping noise and improves sound quality.
The AW8838 supports speaker and receiver 2-in-1 applications. In the receiver application, it connects VDD directly to the Class-D amplifier power supply.
The AW8838 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 AW8838 offers Short Circuit Protection, Over-Temperature Protection, Under-Voltage Protection and Over-Voltage Protection to protect the device.
AW8838 is available in FCQFN 2X3-20L package.
