  • 5V - 2V operation
  • No output coupling capacitors or bootstrap capacitors.
  • Unity-gain stable
  • External gain configuration capability

LM4878IBP Description

    The LM4878 is a bridge-connected audio power amplifier capable of delivering 1 W of continuous average power to an 8 load with less than .2% (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 LM4878 does not require output coupling capacitors or bootstrap capacitors. It is optimally suited for low-power portable applications.

    The LM4878 features an externally controlled, low-power consumption shutdown mode, as well as an internal thermal shutdown protection mechanism.

    The unity-gain stable LM4878 can be configured by external gain-setting resistors.
