Notes:
1. Pin (+) = 1.2 µW and Pin (-) = 0.8 µW.
2. Pin (+) = 100.0 nW and Pin (-) = 1.0 µW.
3. Pin (+) = 1.0 µW and Pin (-) 100.0 nW.
4. Pin (-) held at 1.0 µW while Pin (+) is ramped from 0.5 µW to 1.5 µW and back to 0.5 µW.
5. Pin (+) modulated from 1.0 µW to 2.0 µW. Pin (-) modulated from 1.0 µW to 2.0 µW with phase shifted 180o with respect to 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 placing 1.0 µW of light on the inverting photodiode and ramping the light intensity of the
noninverting input from .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 I.C. chip (Pin (-) = 1.0 µW).
P rise = Value of light power level incident upon the “+”photodiode that is 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 “+”photodiode that is required to switch the digital output when the light level is a
decreasing level (falling edge).
P average = (P rise + P fall)

Application Circuit
OPR5009
Notes:
1. A capacitor of a value between .001 to .01 µF connected as close as possible to the trim terminals is recommended if the device
appears to be susceptable to noise transients. These capacitors will reduce fmax. It is left to the user to determine the best
value for the application.
2. The 74LS04 is recommended as a means of isolating the “DOC”comparator circuitry from transients induced by inductive and
capacitive loads.
3. It is recommeded that a decoupling capacitor be placed as close as possible to the device.
Optek reserves the right to make changes at any time in order to improve design and to supply the best product possible.
