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 from 20 to 200.

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

n Low quiescent current drain: 4mA

n Voltage gains from 20 to 200

The inputs are ground referenced while the output automati-

cally 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.

n Ground referenced input

n Self-centering output quiescent voltage

n Low distortion: 0.2% (A_V= 20, V_S= 6V, R_L= 8Ω, P_O

125mW, f = 1kHz)

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
