NTE784 IC 1W Multi-Purpose Wide-Band Power Amplifier 12-Lead Metal Can

Formerly: ECG784

Integrated Circuit Wide-Band Power Amplifier

Description:

The NTE784 is a multi-stage, multi-purpose, wide-band power amplifier on a single monolithic silicon chip. This device employs a highly versatile and stable direct-coupled circuit configuration featuring wide frequency range, high voltage and power gain, and high power output. These features plus inherent 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:

• High Power Output
• Wide Frequency Range
• High Power Gain
• Single Power Supply for Class B Operation with Transformer
• Built-In Temperature Tracking Voltage RTegulator Provides Stable Operation

Applications:

• AF Power Amplifier for Portable and Fixed Sound and Communications Systems
• Servo-Control Amplifier
• Wide-Band Linear Mixers
• Video Power Amplifiers
• Transmission-Line Driver Amplifier (Balanced and Unbalanced)
• Fan0In and Fan-Out Amplifiers for Computer Logic Circuits
• Lamp-Control Amplifiers
• Motor-Control Amplifiers
• Power Multivibrators
• Power Switches
