LM4872

The LM4872 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 LM4872 does not require output coupling capacitors or bootstrap capacitors. It is optimally suited for low-power portable applications.

The LM4872 features an externally controlled, low-power consumption shutdown mode, as well as an internal thermal shutdown protection mechanism.

The unity-gain stable LM4872 can be configured by external gain-setting resistors.

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.
