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
