LM380

Audio Power Amplifier

A selected part for more power on higher supply voltages is

available as the LM384. For more information see AN-69.

General Description

The LM380 is a power audio amplifier for consumer applica-

tion. In order to hold system cost to a minimum, gain is inter-

nally fixed at 34 dB. A unique input stage allows inputs to be

ground referenced. The output is automatically self centering

to one half the supply voltage.

Features

n Wide supply voltage range

n Low quiescent power drain

n Voltage gain fixed at 50

n High peak current capability

n Input referenced to GND

n High input impedance

The output is short circuit proof with internal thermal limiting.

The package outline is standard dual-in-line. A copper lead

frame is used with the center three pins on either side com-

prising a heat sink. This makes the device easy to use in

standard p-c layout.

n Low distortion

Uses include simple phonograph amplifiers, intercoms, line

drivers, teaching machine outputs, alarms, ultrasonic driv-

ers, TV sound systems, AM-FM radio, small servo drivers,

power converters, etc.

n Quiescent output voltage is at one-half of the supply

voltage

n Standard dual-in-line package
