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.
