Notes: (1) Solder time less than 5 seconds at temperature extreme. (2) Pin (+) = 100.0 nW and Pin (-) = 1.0 µW . (3) Pin (+) = 1.0 µW and Pin (-) = 100.0 nW. (4) 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. (5) 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 k 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 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 “+” photodiode 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 “+” photodiode that is required to switch the digital output when the light level is decreasing level (falling edge). P average = (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.
