Features No output coupling capacitors, bootstrap capacitors or snubber circuits are necessary Small Outline or DIP packaging Unity-gain stable External gain configuration capability Pin compatible with LM4861 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. Key Specification THD+N for 500mW continuous average output power at 1kHz into 8 1% (max) Output power at 10% THD+N at 1kHz into 8 825mW (typ) Shutdown Current 0.7µA (typ) Applications Portable computers Cellular phones Toys and games

Reliability Metrics

Part Number	Process	EFR Reject	EFR Sample Size	PPM	LTA Rejects	LTA Device Hours	FITS	MTTF (Hours)
LM4862M	CS065	2	47473	43	0	5527000	1	1568301341
LM4862MX	CS065	2	47473	43	0	5527000	1	1568301341

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.
