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)
