The LM380 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 package outline is standard dual-in-line. 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, small servo drivers, power converters, etc.
