NTE7016
Integrated Circuit
FM IF System
Description:
The NTE7016 is a monolithic integrated circuit that provides all the functions of a comprehensive FM–
IF system. This device includes a three–stage FM–IF amplifier/limiter configuration with level detectors for each stage, a doubly–balanced quadrature FM detector, and an audio amplifier that features
the optional use of a muting (squelch) circuit.
The advanced circuit design of the IF system includes desirable deluxe features such as programmable delayed AGC for the RF tuner , an AFC drive circuit, and an output signal to drive a tuning meter
and/or provide stereo switching logic. In addition, internal power supply regulators maintain a nearly
constant current drain over the voltage supply range of +8.5 to +16 volts.
The NTE7016 is ideal for high fidelity operation. Distortion in an NTE7016 FM–IF System is primarily
a function of the phase linearity characteristic of the outboard detector coil.
The NTE7016 is available in a 16–Lead DIP type plastic package and can operate over the ambient
temperature range of –40°C to +85°C.
