Product Summary

The LM386 is a Low Voltage Audio Power Amplifier. 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 up to 200. The LM386 is designed for use in low voltage consumer applications. The inputs are ground referenced while the output is automatically biased to one half the supply voltage. The quiescent power drain is only 24 milliwatts when operating from a 6 volt supply, makes the LM386 ideal for battery operation. The applications of the LM386 are AM-FM radio amplifiers, Portable tape player amplifiers, Intercoms, TV sound systems, Line drivers, Ultrasonic drivers, Small servo drivers, Power converters.
