NTE784
Integrated Circuit
Wide–Band Power Amplifier
Description:
The NTE784 is a multistage, multipurpose, wide–band power amplifier on a single monolithic silicon
chip. This device employs a highly versitile and stable direct–coupled circuit configuration featuring
wide frequency range, high voltage and power gain, and high power output. These features plus in-
herent stability over a wide temperature range make the NTE784 extremely useful for a wide variety
of applications in military, industrial, and commercial equipment.
The NTE784 is particularly suited for service as a class B power amplifier and can provide a maximum
power output of 1W from a 12V DC supply with a typical power gain of 75dB.
Features:
D High Power Output
D Wide Frequency Range
D High Power Gain
D Single Power Supply for Class B Operation with Transformer
D Built–In Temperature Tracking Voltage Regulator Provides Stable Operation
Applications:
D AF Power Amplifiers for Portable and Fixed Sound and Communications Systems
D Servo–Control Amplifier
D Wide–Band Linear Mixers
D Video Power Amplifiers
D Transmission–Line Driver Amplifier (Balanced and Unbalanced)
D Fan–In and Fan–Out Amplifiers for Computer Logic Circuits
D Lamp–Control Amplifiers
D Motor–Control Amplifiers
D Power Multivibrators
D Power Switches
