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 -40C to +85C.
