GENERAL DESCRIPTION
Boomer audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external components using surface mount packaging. Since the LM4861 does not require output coupling capacitors, bootstrap capacitors, or snubber networks, it is optimally suited for low-power portable systems. Key Specifications n THD at 1 kHz at 1W continuous average output power into 8Ω n Output power at 10% THD+N at 1 kHz into 8Ω n Shutdown Current 1.0% (max) 1.5W (typ) 0.6 µA (typ) FEATURES
n No output coupling capacitors, bootstrap capacitors, or snubber circuits are necessary n Small Outline (SO) packaging n Compatible with PC power supplies n Thermal shutdown protection circuitry n Unity-gain stable n External Gain Configuration Capability APPLICATIONS
