FEATURES DESCRIPTION
The LM380 is a power audio amplifier for consumer
• Wide Supply Voltage Range: 10V-22V
applications. In order to hold system cost to a
• Low Quiescent Power Drain: 0.13W (VS= 18V) minimum, gain is internally fixed at 34 dB. A unique
• Voltage Gain Fixed at 50 input stage allows ground referenced input signals.
• High Peak Current Capability: 1.3A The output automatically self-centers to one-half the
supply voltage.
• Input Referenced to GND
The output is short circuit proof with internal thermal • High Input Impedance: 150kΩ
limiting. The package outline is standard dual-in-line.
• Low Distortion The LM380N uses a copper lead frame. The center
• Quiescent Output Voltage is at One-Half of the three pins on either side comprise a heat sink. This
Supply Voltage makes the device easy to use in standard PC layouts.
• Standard Dual-In-Line Package 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.
A selected part for more power on higher supply
voltages is available as the LM384. For more
