LM380N-8

BRAND NEW & ORIGINAL

PACKAGE: 8 PIN DIP

The LM380 is a power audio amplifier for consumer application. In order to hold system cost to a minimum, 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 circuit proof with internal thermal limiting. The package outline is standard dual-in-line, eight pin. 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 PC layouts. Uses include, simple phonograph amplifiers, intercoms, line drivers, teaching machine outputs, alarms, ultrasonic drivers, TV sound systems, AM-FM radio, small servo drivers, power converters, etc.
