AW88081DNR is an I2S/TDM/PDM input digital audio amplifier. Due to its 9µV noise floor and ultra-low distortion, clean listening is guaranteed. It can deliver 3.2W output power into an 4Ω speaker at 10% THD+N. AW88081DNR 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. Two devices can be combined to build a stereo application. AW88081DNR offers Short Circuit Protection, Over-Temperature Protection, Under-Voltage Protection and Over-Voltage Protection to protect the device. AW88081DNR is available in a WBDFN 3X3-12L(0.85).
