The LM384 is a power audio amplifier for consumer applications. In order to hold system cost to a minimum, the 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 three center pins on either side comprising a heat sink. This makes the device easy to use in a standard P-C layout. Uses include simple phonograph amplifiers, intercoms, line drivers, teaching machine outputs, alarms, ultrasonic drivers, TV sound systems, AM-FM radio, sound projector systems, etc.
