LM386

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 volt supply, making the

LM386 ideal for battery operation.
