Description:

The NTE1791 is a silicon monolithic integrated circuit in a 9–Lead SIP type package designed for remote 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 characteristics by use of a two–stage tuning circuit.

The NTE1791 output polarity is active “LOW”.

Features:

• Good Immunity from Light Interference: Narrow Bandwidth ±1.3kHz Typ.

• Operation Voltage: 6V ±10%

• Low Power Consumption: 2.4mA Typ.

• High Input Sensitivity: 50µVP–P Typ.

• Peak Detector: The Detector Level is Varied with the Input Signal Level.

• Output Terminal: Open Collector Output. Easy to Interface to Other Devices.
