Integrated Circuit
FM/AM IF System
Description:
The NTE1842 is a FM/AM IF system IC in a 16–Lead DIP type package designed for portable use.
As compared with conventional ICs, this device is greatly improved in external parts counts and elec-
trical characteristics, espeically tweet and overload distortions.
Features:
Low Supply Current, AM: 7mA, FM: 10mA (Typ)
Low Number of External Components
Excellent Tweet
Low Overvoltage Distortion
