NTE862
Integrated Circuit
Audio Power Amplifier, 5W
Description:
The NTE862 is a power audio amplifier in a 14−Lead DIP type package designed for use in consumer
applications. In order to hold system cost to a minimum, the gain is internally fixed at 34dB. A unique
input stage allows the inputs to be ground referenced. The output is automatically self centering to
one half the supply voltage.
Uses include simple phonograph amplifiers, intercoms, line drivers, teaching machine outputs,
alarms, ultrasonic drivers, TV sound systems, AM−FM radio, sound projector systems, etc.
Features:
D Wide Supply Voltage Range
D Low Quiescent Power Drain
D Voltage Gain Fixed at 50
D High Peak Current Capability
D Input Referenced to GND
D High Input Impedance
D Low Distortion
D Quiescent Output Voltage is at One Half of the Supply Voltage
