Internal Reference: LM386

General 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.

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=8W, PO=125mW, f=1kHz)
  • Available in 8 pin MSOP package

Applications:

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