APA4863 APA4863 Stereo 2.2W Audio Power Amplifier Features General Description · · · The APA4863 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 APA4863 is capable of delivering 2.2W/1.8W/1.2W of continuous RMS power per channel into 3/4/8 bridge-tied loads with less than 1% THD+N respectively . When APA4863 APA4863 operates in the single-ended load , it is capable of delivering 90mW of continuous RMS power per channel into 32 load . The APA4863 APA4863 simplifies design and frees up board space for other features . Depop Circuitry Integrated Thermal Shutdown Circuitry Integrated Bridge-Tied Load (BTL) or Single-Ended (SE) Modes Operation · Output Power at 1% THD+N, VDD=5V - 2.2W/Ch (typ) into a 3 Load - 1.8W/Ch (typ) into a 4 Load - 1.2 W/Ch (typ) into a 8 Load · · Shutdown Control Mode, ISD= 0.5 µA The APA4863 APA4863 also served well in low-voltage applications , which provides 750mW (1% THD+N) per channel into 4 loads with a 3.3V supply voltage . Both of the depop circuitry and the thermal shutdown protection circuitry are integrated in the APA4863 APA4863 , that reduces pops and clicks noise during power up and when using the shutdown mode and protects the chip from being destroyed by over-temperature failure . To simplify the audio system design in notebook computer applications , the APA4863 APA4863 combines a stereo bridge-tied loads mode for speaker drive and a stereo single-end mode for headphone drive into a single chip , where both modes are easily switched by the HP-IN input control pin signal . For power sensitive applications , the APA4863 APA4863 also features a shutdown function which keeps the supply current only 0.5 µA (typ.) . Output Power (SE) at 0.5% THD+N, VDD=5V - 90mW/Ch (typ.) into a 32 Load · Various Power Packages Available SOP, TSSOP, TSSOP-P Applications · Stereo Audio Power Amplifier for Notebook Computer · · Portable Televisions Portable and Desktop Computers Ordering Information Package Code K: SOP O: TSSOP Temp.
