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 180°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% ponts.
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
noninverting input from .5µW 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 “+”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
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.
Optek reserves the right to make changes at any time in order to improve design and to supply the best product possible.
