NTE7013
Integrated Circuit
Remote Control Preamp with Active “Low”
Description:
The NTE7013 is a bipolar integrated circuit in an 8–Lead DIP type package intended for infrared re-
mote control applications. This device has an active “Low” output polarity and contains a high–gain
amplifier, a limiter amplifier, a band–pass filter, a detector, and a pulse shaper.
