LOW VOLTAGE AUDIO POWER

AMPLIFIER

DESCRIPTION

The UTC 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 pin 1 and pin 8 will increase the gain to any value up from 20 to

200.

The inputs are ground referenced while the output automatically biases

to one-half the supply voltage. The quiescent power drain is only 24

milliwatts when operating from a 6 voltage supply, making the LM386

ideal for battery operation.
