February 2000 LM4871 1.1W Audio Power Amplifier with Shutdown Mode General Description Key Specifications The LM4871 is a bridge-connected audio power amplifier ca- n THD at 1 kHz at 1W continuous pable of delivering typically 1.1W of continuous average average output power into 8Ω 0.5% (max) power to an 8Ω load with 0.5% (THD) from a 5V power sup- n Output power at 10% THD+N ply. 1.5W (typ) at 1 kHz into 8Ω Boomer audio power amplifiers were designed specifically to n Shutdown Current 0.6 µA (typ) provide high quality output power with a minimal amount of external components. Since the LM4871 does not require output coupling capacitors, bootstrap capacitors, or snubber Features networks, it is optionally suited for low-power portable sys- n No output coupling
