LM384 5W Audio Amplifier – Datasheet

2,780 views

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 inputs to be ground referenced. The output is automatically self-centering to one-half the supply voltage. The output is short-circuited 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. Uses include simple phonograph amplifiers, intercoms, line drivers, teaching machine outputs, alarms, ultrasonic drivers, TV sound systems, AM-FM radio, sound projector systems.
