Features • Active-high shutdown mode • LLP, MSOP, and SO surface mount packaging • "Click and Pop" suppression circuitry • Low shutdown current • No bootstrap capacitors required • Unity-gain stable Description The LM4810 is a dual audio power amplifier capable of delivering 105mW per channel of continuous average power into a 16 load with 0.1% (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 LM4810 does not require bootstrap capacitors or snubber networks, it is optimally suited for low-power portable systems. The unity-gain stable LM4810 can be configured by external gain-setting resistors. The LM4810 features an externally controlled, active-high, micropower consumption shutdown mode, as well as an internal thermal shutdown protection mechanism. Key Specification THD+N at 1kHz, 105mW continuous average power into 16 0.1% (typ) THD+N at 1kHz, 70mW continuous average power into 32 0.1% (typ) Shutdown Current 0.4µA (typ) Applications • Cellular Phones • Personal Computers • Microphone Preamplifier • PDA's

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.
