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.
