LM386

Low Voltage Audio Power Amplifier

General Description

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.

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.
