General Description
The LM4862 is a bridge-connected audio power amplifier capable of delivering typically 675mW of continuous
average power to an 8Ohm load with 1% THD+N 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 LM4862 does not require output coupling capacitors,
bootstrap capacitors, or snubber networks, it is optimally suited for low-power portable systems.
The LM4862 features an externally controlled, low-power consumption shutdown mode, as well as an internal
thermal shutdown protection mechanism.
The unity-gain stable LM4862 can be configured by external gain-setting resistors.
