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.
The output automatically self-centers to one-half the
High Peak Current Capability: 1.3A
supply voltage.
Input Referenced to GND
The output is short circuit proof with internal thermal
High Input Impedance: 150k
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
information see SNAA086.
