333 3 VSOP98260 www.vishay.com Vishay Semiconductors Preamplifier Circuit for IR Remote Control FEATURES Carrier-out-function: carrier frequency and burst length accurately correspond to the input signal AC coupled response from 20 kHz to 60 kHz all data formats Small QFN package with 2 mm width Can be used with either a photodiode or an IR emitter i n forward or reverse polarity AC coupled input is insensitive to DC photocurrents Material categorization: for definitions of compliance 22906 please see www.vishay.com/doc 99912 ESD LINKS TO ADDITIONAL RESOURCES To maximize the sensitivity, the TIA input pin has minimal ESD protection. Care should be taken never to touch or 3D Models otherwise expose this pin to an adverse ESD source. The ESD protection conforms to Class 1B MECHANICAL DATA DESCRIPTION Pinning: The VSOP98260 is designed for use in an IR learning 1, 4, 5= N.C., 2 = V , 3 = OUT, 6, 8 = GND, 7 = IN S application together with a photo PIN diode or IR LED as optical detector. It is compatible with all data formats for IR remote control. On the other hand it is immune to current caused by light sources such as tungsten bulbs or fluorescent lamps.
