Description: Each OPR5011 device is a hybrid sensor array that consists of three channels of the OPTEK OPC8332 differential optical comparator (‘TRI-DOC”) IC. The single chip construction ensures very tight dimensional tolerances between active areas. Specifically designed for high-speed/high-resolution encoder applications, the open collector output switches based on the comparison of the input photodiode’s light current levels. Logarithmic amplification of the input signals facilitates operation over a wide range of light levels. The surface-mountable opaque polyimide package shields the photodiodes from stray light and can withstand multiple exposures to the most demanding soldering conditions, while the gold-plated wraparound contacts provide exceptional storage and wetting characteristics. Features:

  • Precise active area location
  • Surface mountable
  • TTL compatible output
  • Wide supply voltage range
  • Wide operating temperature range Applications:
  • High-speed applications
  • High-resolution applications
  • Applications requiring a wide range of light levels RoHS Part Number Sensor # of Elements Icc (mA) Typ / Max Optical Hysteresis (%) Typical Optical Offset (%) Min / Max OPR5011 Differential Optical Comparator 3 9 / 20 40.00 -40/+40

Notes: (1) The 74L2)4 is recommended as a means of isolating the “DOC” comparator circuitry from transients induced by inductive and capacitive loads. (2) It is recommended that a decoupling capacitor be placed as close as possible to the device. Block Diagram - OPC8332

(2) Pin (+) = 100.0 nW and Pin (-) = 1.0 µW . (3) Pin (+) = 1.0 µW and Pin (-) = 100.0 nW. Pin (+). Use 100 kΩ trimpot to set the output signal to 50% duty cycle for maximum operating frequency. (6) Measured between 10% and 90% points. (7) Optical Hysteresis and Optical Offset are found by placi ng 1.0 µW of light on the inverting photodiode and ramping the light intensity of the non-inverting input from 0.5 µW up to 1.5 µW and back down. This will produce two trigger points – an upper trigger point and lower trigger point. These points are used to calculate the optical hysteresis and offset. These are defined as: % Optical Hysteresis = 100 x (P rise - P fall) P in (-) % Optical Offset = 100 x (P average - P (-)) P in (-) Where: P in (-) = Light level incident upon the “-” photodiode on the IC chip (Pin) (-) = 1.0 µW). P rise = Value of light power level incident upon the “+” pho todiode that his required to switch the digital output when the light level is an increasing level (rising edge). P fall = Value of light power level incident upon the “+” pho todiode that is required to switch the digital output when the light level is decreasing level (falling edge). P average = (P rise + P fall)
