VSOP383.. www.vishay.com Vishay Semiconductors Preamplifier Circuit for IR Remote Control (valid July 2016 onwards) FEATURES Narrow bandpassfilter for all common carrier frequencies High immunity against DC light Intelligent AGC to suppress disturbance from fluorescent lamps and CRTs Low power consumption Wide supply voltage range High immunity against ripple on the supply voltage Output active low IC manufactured in CMOS technology 22906 Small QFN package with 2 mm width Material categorization: for definitions of compliance please see www.vishay.com/doc 99912 click logo to get started DESIGN SUPPORT TOOLS DESCRIPTION Models The VSOP383.. is designed for use in an IR receiver Available application together with a photo pin diode. It is a sophisticated receiver concept that is very sensitive to data MECHANICAL DATA signals and compatible with the most common data formats Pinning: for IR remote control. On the other hand it is immune to DC current caused by DC light sources such as tungsten bulbs. 1, 4, 5 = N.C., 2 = V , 3 = OUT, 6, 8 = GND, 7 = IN S The disturbance signal of fluorescent lamps is suppressed there are no unwanted pulses at the output.

We recommend 2 2.3 mm area. The connection between the photodiode and to keep the distance between the photodiode and the input pin 7 should be kept as short as possible and carefully of the VSOP383.. as short as possible. 21537-4 shielded to prevent noise coupling.
