LM389N DIP IC

DESCRIPTION
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 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
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 SNAA086.
