DESCRIPTION
The LM384 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.
A copper lead frame is used with the center three
pins on either side comprising 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 drivers, TV sound systems, AM-FM
radio and sound projector systems. See SNAA086 for
circuit details.
