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 in-
ternally fixed at 34 dB. A unique input stage allows ground
referenced
input
signals.
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 com-
prising 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.
