LM380 2.5W Audio Power Amplifier
August 2000
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.
A selected part for more power on higher supply voltages is
available as the LM384. For more information see AN-69.
