LM386 Datasheet Low Voltage Audio Power Amplifier

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LM386 Low Voltage Audio Power Amplifier January 2000 LM386 Low Voltage Audio Power.

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 up to 200.

The inputs are ground referenced while the output is automatically biased to one half the supply voltage.

Key Features

  • n n n n n n n n n Battery operation Minimum external parts Wide supply voltage range: 4V.
  • 12V or 5V.
  • 18V Low quiescent current drain: 4 mA Voltage gains from 20 to 200 Ground referenced input Self-centering output quiescent voltage Low distortion Available in 8 pin MSOP package.
