AW88084A is a member of the AW88084A/B/C/D series. This series comprises four models (A/B/C/D) of I2S/TDM input digital audio amplifiers. The digital audio interface configuration is achieved via resistor pull-up on the EN pin, eliminating the need for I2C programming.
The AW88084A/B/C/D series ensures clean audio performance with a 10µV noise floor and ultra-low distortion, while delivering 3.2W output power into 4Ω speakers at 10% THD+N.
The AW88084A/B/C/D series features high RF suppression and eliminates TDD noise completely benefited from the digital audio input interface.
The AW88084A/B/C/D series support spread spectrum and edge-rate limiting to enhance EMI performance while reduces output filter size and cost.
The AW88084A/B/C/D series offers Short Circuit Protection, Over-Temperature Protection, Under-Voltage Protection to protect the device.
AW88084A/B have a fast 1ms turn-on time, while AW88084C/D ramp the volume over 13ms during turn-on and turn-off.
The AW88084A/B/C/D series is available in a WLCSP 1.403mmX1.183mm-9B package. All versions share identical pin definitions.
