NTE1764 Integrated Circuit Infrared Preamplifier Description: The NTE1764 is an infrared preamplifier in a 14–Lead DIP type package and contains four main parts: the gain–controlled amplifier I, the amplifier II, the pulse–separating amplifier III, and the inverter IV.
The amplifier I has a wide dynamic range and thus ensures interference free operation, also at bright ambient light, 50Hz modulated light originating from fluorescent lamps, or at intensive infrared light, e.

produced by infrared sound transmission.
It is also possible, to approach almost directly the remote–control transmitter to the receiver without producing misfunction by overdriving the receiver.
The amplifier II furthe...
