Each
OPR5011
device is a hybrid sensor array that consists of three channels of the OPTEK 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.
See Application Bulletin 237 for handling instructions.

Notes:
(1) The 74LS04 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.

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 =

= 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).
