NTE1791
Integrated Circuit
TV Remote Control Amplifier
Description:
The NTE1791 is a silicon monolithic integrated circuit in a 9鈥揕ead SIP type package designed for re-
mote control preamplification of infrared signals. A PIN photo diode can be directly connected to the
input terminal.
This device contains a high gain amplifier, a peak detector, and an output waveform shaper which are
necessary for a remote control preamplifier and has improved light interference鈥搑ejection character-
istics by use of a two鈥搒tage tuning circuit.
The NTE1791 output polarity is active 鈥淟OW鈥?
