Overview

NTE1292 Integrated Circuit IF Amplifier and Detector Description: The NTE1292 is a monolithic integrated circuit in a 14–Lead DIP type package specifically designed for audio detection in TV and FM radio receivers.
It incorporates an 8–stage limiting IF amplifier and balanced detector plus a DC operated volume control.
Pin3 and Pin4 are connected to the collector and base of a transistor which may be used as an AF– preamplifier or as a switch.
At Pin12 a zener–diode is accessible which can be used to stabilize the supply voltage of this integrated circuit or the voltage of other circuit elements in the set.
