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 3Ω/4Ω/8Ω 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 32Ω load . The APA4863 simplifies design and frees up board space for other features .
