Optical Comparator Array OPR5011 Features: • • • • • Precise active area location Surface mountable TTL compatible output Wide supply voltage range Wide operating temperature range 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. Applications: • • • Ordering Information High-speed applications High-resolution applications Applications requiring a wide range of light levels Part Number Sensor Differential Optical OPR5011 Comparator Optical # of Icc (mA) Hysteresis (%) Elements Typ / Max Typical 3 9 / 20 40.00 Optical Offset (%) Min / Max -40/+40 NOTE: SEE PAGE 2 FOR APPLICATION CIRCUIT.

Pin (+) = 100.0 nW and Pin (-) = 1.0 µW . Pin (+) = 1.0 µW and Pin (-) = 100.0 nW. Pin (-) is held at 1.0 µW while Pin (+) is ramped from 0.5 µW to 1.5 µW and back to 0.5 µW. Pin (+) is modulated from 1.0 µW to 2.0 µW. Pin (-) is modulated from 1.0 µW to 2.0 µW with phase shifted 180° with respect to Pin (+). Use 100 kΩ trimpot to set the output signal to 50% duty cycle for maximum operating frequency. Measured between 10% and 90% points. Optical Hysteresis and Optical Offset are found by placing 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 (-) P rise P fall P average = Light level incident upon the “-” photodiode on the IC chip (Pin) (-) = 1.0 µW). = Value of light power level incident upon the “+” photodiode that his required to switch the digital output when the light level is an increasing level (rising edge). = Value of light power level incident upon the “+” photodiode that is required to switch the digital output when the light level is decreasing level (falling edge). = (P rise + P fall) 2 OPTEK reserves the right to make changes at any time in order to improve design and to supply the best product possible.
