Optical Comparator Arrays
Type OPR5001B, OPR5002B, OPR5003B
Features Surface mountable Multiple channels available compatible output Wide supply voltage range Description
OPR5001B, OPR5002B OPR5003B hybrid sensor arrays consisting one, three channels Optek OPC8032 Differential Optical Comparator, DOC" Specifically designed encoder applications, open collector output switches based comparison input photodiode' light current levels. Logarithmic amplification input signals makes possible operation over wide range light levels. packages surface mountable made from custom opaque polyimide which shields active devices from stray light. high temperature laminate withstand multiple exposures most demanding soldering conditions. Wrap around contacts gold plated exceptional storage wetting characteristics. Replaces OPR5001A Series.

Optical Hysteresis Optical Offset found placing light inverting photodiode ramping light intensity noninverting input from back down. This will produce trigger points, upper trigger point lower trigger point. These points used calculate optical hysteresis offset. These defined Optical Hysteresis rise fall) Optical Offset average Where: Light level incident upon photodiode I.C. chip (Pin µW). rise Value light power level incident upon photodiode that required switch digital output when light level increasing level (rising edge). fall Value light power level incident upon photodiode that required switch digital output when light level decreasing level (falling edge). average rise fall)
Application Circuit
OPR5001B
Notes: capacitor value between .001 connected close possible trim terminals recommended device appears susceptable noise transients. These capacitors will reduce fmax. left user determine best value application. 74LS04 recommended means isolating DOC"comparator circuitry from transients induced inductive capacitive loads. recommeded that decoupling capacitor placed close possible device.
