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.

Features:

• Electronic Attenuator: Replaces Conventional AC Volume Control

• Volume Reduction Range: 85dB Typ

• Sensitivity: 3dB Limiting Voltage 30µV Typ

• Excellent AM Rejection 68dB Typ at 10mV

• Audio Output Voltage: 1V Typ

• Wide Supply Voltage Range: VCC = 6V to 18V

• Internal Zener Diode Regulator

• Very Low External Component Requirement

• Simple Detector Alignment: One Coil
