LM386 - Low Voltage Audio Power Amplifier

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 up to 200.

Features

  • Battery operation.
  • Minimum external parts.
  • Wide supply voltage range 4V to 12V.
  • Low quiescent current drain 4mA (Typ. ).
  • Voltage gains from 20 to 200.
  • ESD Protection 2kV.
  • Ground referenced input.
  • Self-centering output quiescent voltage.
  • Low distortion.
