LM380

2.5W Audio Power Amplifier

General Description

The LM380 is a power audio amplifier for consumer applica-

tions. In order to hold system cost to a minimum, gain is

internally fixed at 34 dB. A unique input stage allows ground

referenced input signals. The output automatically self-

centers to one-half the supply voltage.

The output is short circuit proof with internal thermal limiting.

The package outline is standard dual-in-line. The LM380N

uses a copper lead frame. The center three pins on either

side comprise a heat sink. This makes the device easy to

use in standard PC layouts.

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.
