Optical Comparator Array
Type OPR5010
Features Surface mountable compatible output Wide supply voltage range Description
OPR5010 hybrid sensor array consisting three channels Optek OPC8031 Differential Optical Comparator, DOC-2" Specifically designed high speed/high resolution 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.

Measured between points. 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.
