General  Description

The APA4863 is a stereo bridge-tied audio power amplifier in various power packages, including SOP, TSSOP, and TSSOP-P. When connecting to a 5V voltage supply, the APA4863 is capable of delivering 2.2W/1.8W/1.2W of continuous RMS power per channel into  3W/4 W/8 W bridge-tied loads with less than 1% THD+N respectively. When APA4863 operates in the single-ended load, it is capable of delivering 90mW of continuous RMS power per channel into 32W load. The APA4863 simplifies design and frees up board space for other features.
