LM4862 675 mW Audio Power Amplifier with Shutdown Mode
September 2004
LM4862 675 mW Audio Power Amplifier with Shutdown Mode
General Description
The LM4862 is a bridge-connected audio power amplifier capable of delivering typically 675mW of continuous average power to an 8 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. n Output power at 10% THD+N at 1kHz 8 n Shutdown Current into 825mW (typ) 0.7µA (typ)
