Description

The ATA-120 Class-D Audio Amplifier is a fully integrated monolithic audio amplifier that can provide audio power up to 20 watts @ 10% THD into a 4Ω speaker.

The ATA-120 incorporates a single ended output structure with builtin short circuit and overtemperature protection. This low noise, high performance device delivers the excellent audio quality of a class A/B amplifier while still achie-ving class-D efficiency greater than 90%.
