Low Voltage Audio Power Amplifier LM386N/D

DESCRIPTION

The 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 pins 1 and 8 will increase the

gain to any value 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 D386 ideal for battery operation.
