The NTE788 is a monolithic integrated circuit in a 16Lead DIP type package that provides all the functions of a comprehensive FMIF system. This device features a threestage FMIF amplifier/limiter configuration with level detectors for each stage, a doublybalanced 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 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 +8.5V to +16V. Features:
