LM384

5W Audio Power Amplifier

General Description

The LM384 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. A copper lead

frame is used with the center three pins on either side

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

standard p-c layout.

Uses include simple phonograph amplifiers, intercoms, line

drivers, teaching machine outputs, alarms, ultrasonic driv-

ers, TV sound systems, AM-FM radio, sound projector sys-

tems, etc. See AN-69 for circuit details.
