With the LM4866 packaged in the LLP, the customer benefits include low thermal impedance, low profile, and small size. This package minimizes PCB area and maximizes output power.
The LM4866 features an externally controlled, low-power consumption shutdown mode, and thermal shutdown protection. It also utilizes circuitry to reduce "clicks and pops" during device turn-on.
Boomer audio power amplifiers are designed specifically to use few external components and provide high quality output power in a surface mount package.

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.For more information on Reliability Metrics, please click here.
