Description

The NTE1292 is a monolithic integrated circuit in a 14Lead DIP type package specifically designed for audio detection in TV and FM radio receivers. It incorporates an 8stage 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 zenerdiode of NTE1292 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.
