NTE1791
Integrated Circuit
TV Remote Control Amplifier
Description:
The NTE1791 is a silicon monolithic integrated circuit in a 9–Lead 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–rejection character-
istics by use of a two–stage tuning circuit.
The NTE1791 output polarity is active “LOW”.
Features:
D Good Immunity from Light Interference: Narrow Bandwidth ±1.3kHz Typ.
D Operation Voltage: 6V ±10%
D Low Power Consumption: 2.4mA Typ.
D High Input Sensitivity: 50µVP–P Typ.
D Peak Detector: The Detector Level is Varied with the Input Signal Level.
D Output Terminal: Open Collector Output. Easy to Interface to Other Devices.
Absolute Maximum Ratings: (TA = +25°C unless otherwise specified)
