LM380
Audio Power Amplifier
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.
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, small servo drivers,
power converters, etc.
A selected part for more power on higher supply voltages is
available as the LM384. For more information see AN-69.
