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.
