The LM4871 is a bridge-connected audio power amplifier capable of delivering typically 1.1W of continuous average power to an 8 load 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 LM4871 does not require output coupling capacitors, bootstrap capacitors, or snubber networks, it is optionally suited for low-power portable systems. The LM4871 features an externally controlled, low-power consumption shutdown mode, as well as an internal thermal shutdown protection mechanism. The unity-gain stable LM4871 can be configured by external gain-setting resistors.
