NTE1578
Integrated Circuit
FM Mixer/IF Amp
Description:
The NTE1578 is an FM front–end integrated circuit in a 16–Lead DIP type package designed for use
in car radio and home stereo applications. This device has a built–in AGC driver circuit which im-
proves interference characteristics. It thereby offers advantages such as improved interference char-
acteristics without sacrificing usable sensitivity and the conventional DX–LOCAL change–over
switch.
Features:
D Double–Balanced Type MIX (Improved Spurious Characteristic)
D Keyed AGC/Keyed Classical AGC (Improved Intermodulation, Cross Modulation Characteristic)
D Differential IF Amplification (Improved Limiting Characteristic)
Absolute Maximum Ratings: (TA = +25°C unless otherwise specified)
