AF4871A datasheet



The AF4871A is a bridge-connected audio power amplifier capable of delivering typically 1W of continuous average power to an 8Ωload with 0.5% (THD) from a 5V power supply.

Boomer audio power amplifiers were designed Specifically to provide high quality output power with a minimal amount of external components. Since the AF4871A does not require output coupling Capacitors, bootstrap capacitors, or snobbier networks, it is optionally suited for low-power portable systems.




1. THD at 1 kHz at 1W continuous average output power into 8W 0.5%
2. Output power at 10% THD+N at 1 kHz into 8W 1.5W
3. Shutdown Current 0.6 μA


1. Portable Computers
2. Desktop Computers
3. Low Voltage Audio Systems
