LM386

Low Voltage Audio Power Amplifier

General Description

Features

n Battery operation

n Minimum external parts

The LM386 is a power amplifier designed for use in low volt-

age 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.

n Wide supply voltage range: 4V–12V or 5V–18V

n Low quiescent current drain: 4 mA

n Voltage gains from 20 to 200

The inputs are ground referenced while the output is auto-

matically biased to one half the supply voltage. The quies-

cent power drain is only 24 milliwatts when operating from a

6 volt supply, making the LM386 ideal for battery operation.

n Ground referenced input

n Self-centering output quiescent voltage

n Low distortion

n Available in 8 pin MSOP package

Applications

n AM-FM radio amplifiers

n Portable tape player amplifiers

n Intercoms

n TV sound systems

n Line drivers

n Ultrasonic drivers

n Small servo drivers

n Power converters
