DATA SHEET

LND386

LOW VOLTAGE AUDIO POWER AMPLIFIER

GENERAL DESCRIPTION

The LND386 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 up to 200.

The inputs are ground referenced while the

output is automatically biased to one half the

supply voltage. The quiescent power drain is

only 24 milliwatts when operating from a 6 volt

supply, making the LND386 ideal for battery

operation.
