LM380N-8 DIP IC

The LM380 is a power audio amplifier for consumer applications. 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 selfcenters 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 drivers, 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.
