The NTE7016 is a monolithic integrated circuit that provides all the functions of a comprehensive FM鈥?/div>
IF system. This device includes a three鈥搒tage FM鈥揑F amplifier/limiter configuration with level detec-
tors for each stage, a doubly鈥揵alanced 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 program-
mable 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鈥揑F System is primarily
a function of the phase linearity characteristic of the outboard detector coil.
The NTE7016 is available in a 16鈥揕ead DIP type plastic package and can operate over the ambient
temperature range of 鈥?0擄C to +85擄C.
