Features • 2W/channel • -65 dB ripple rejection, output referred • -65 dB channel separation, output referred • Wide supply range, 6V-24V • Very low cross-over distortion • Low audio band noise • AC short circuit protected • Internal thermal shutdown Description The LM1877 is a monolithic dual power amplifier designed to deliver 2W/channel continuous into 8 loads. The LM1877 is designed to operate with a low number of external components, and still provide flexibility for use in stereo phonographs, tape recorders and AM-FM stereo receivers, etc. Each power amplifier is biased from a common internal regulator to provide high power supply rejection, and output Q point centering. The LM1877 is internally compensated for all gains greater than 10. Applications • Multi-channel audio systems • Stereo phonographs • Tape recorders and players • AM-FM radio receivers • Servo amplifiers • Intercom systems • Automotive products

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.
