XA8123 - 2x20W Stereo / 1x40W Mono Class-D Audio Amplifier

Download the XA8123 datasheet PDF. This datasheet also covers the XA8123-X variant, as both devices belong to the same 2x20w stereo / 1x40w mono class-d audio amplifier family and are provided as variant models within a single manufacturer datasheet.

Description

XA8123 is a high-performance digital audio amplifier IC that delivers up to 20W×2ch, which has a digital audio interface, and is capable of operating at a supply voltage ranging from 5V to 26V.

XA8123 allows a speaker to be directly connected to the output.
