UPC2807 Datasheet (NEC) - PREAMPLIFIER FOR INFRARED REMOTE CONTROLLER

UPC2807, PREAMPLIFIER FOR INFRARED REMOTE CONTROLLER

The µ PC2807 and 2807A are semiconductors integrated circuit developed as preamplifiers for the receiver module of infrared remote controllers.

These preamplifiers can be directly connected to a PIN photodiode, and integrate a high-gain first stage amplifier, limiter, bandpass filter, detector circu
