Features • Battery operation • Minimum external parts • Wide supply voltage range: 4V-12V or 5V-18V • Low quiescent current drain: 4mA • Voltage gains from 20 to 200 • Ground referenced input • Self-centering output quiescent voltage • Low distortion: 0.2% (AV = 20, VS = 6V, RL = 8Ohm, PO = 125mW, f = 1kHz) • Available in 8 pin MSOP package Description The LM386 is a power amplifier designed for use in low voltage consumer applications. The gain is internally set to 20 to keep external part count low, but the addition of an external resistor and capacitor between pins 1 and 8 will increase the gain to any value from 20 to 200. The inputs are ground referenced while the output automatically biases to one-half the supply voltage. The quiescent power drain is only 24 milliwatts when operating from a 6 volt supply, making the LM386 ideal for battery operation. Applications • AM-FM radio amplifiers • Portable tape player amplifiers • Intercoms • TV sound systems • Line drivers • Ultrasonic drivers • Small servo drivers • Power converters

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.
