www.DataSheet.co.kr VSOP584.. www.vishay.com Vishay Semiconductors Preamplifier Circuit for IR Remote Control 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 22529 IC manufactured in CMOS technology Small QFN package with 2 mm width Compliant to RoHS Directive 2002/95/EC Note ** Please see document “Vishay Material Category Policy”: www.vishay.com/doc?99902 MECHANICAL DATA Pinning: 1, 4, 5= N.C., 2 = VS, 3 = OUT, 6, 8 = GND, 7 = IN DESCRIPTION The VSOP584.. is designed for use in an IR receiver application together with a photo pin diode. It is a sophisticated receiver concept that is very sensitive to data signals and compatible with the most common data formats for IR remote control. On the other hand it is immune to DC current caused by DC light sources such as tungsten bulbs. The disturbance signal of fluorescent lamps is suppressed; there are no unwanted pulses at the output.
