Texas Instruments LM384N

LM384N Description
:
The LM384N is a power audio amplifier for consumer 2? Wide Supply Voltage Range: 12V to 26V
applications. In order to hold system cost to a minimum, gain is internally fixed at 34 dB. A unique
? Low Quiescent Power Drain 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.
