Features
  • No bootstrap capacitors or snubber circuits are necessary
  • Small Outline (SO) and DIP packaging
  • Unity-gain stable
  • External gain configuration capability

    • Description

    The LM4880 is a dual audio power amplifier capable of delivering typically 250mW per channel of continuous average power to an 8 load with 0.1% THD+N using a 5V power supply.

    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 LM4880 does not require bootstrap capacitors or snubber networks, it is optimally suited for low-power portable systems.

    The LM4880 features an externally controlled, low-power consumption shutdown mode, as well as an internal thermal shutdown protection mechanism.

    The unity-gain stable LM4880 can be configured by external gain-setting resistors.

    Key Specification

  • THD+N at 1kHz at 200mW continuous average output power into 8: 0.1% (max)

    Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
