LM386 Low Voltage Audio Power Amplifier

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.

Features

  • Wide supply voltage range: 4V-12V
  • Low quiescent current drain: 4mA
  • Output Power: 325mW
  • Voltage gains from 20 to 200
  • Battery operation
  • Low distortion: 0.2%
  • 8-pin SOIC package

    Applications

  • AM-FM radio amplifiers
  • Portable tape player amplifiers
  • Intercoms
  • TV sound systems
  • Line drivers
  • Ultrasonic drivers
  • Small servo drivers
  • Power converters
