Notes:
(1) Solder time less than 5 seconds at temperature extreme.
(2) Pin (+) = 100.0 nW and Pin (-) = 1.0 礧 .
(3) Pin (+) = 1.0 礧 and Pin (-) = 100.0 nW.
(4) Pin (-) is held at 1.0 礧 while Pin (+) is ramped from 0.5 礧 to 1.5 礧 and back to 0.5 礧.
(5) Pin (+) is modulated from 1.0 礧 to 2.0 礧. Pin (-) is modulated from 1.0 礧 to 2.0 礧 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 礧 of light on the inverting photodiode and ramping the light
intensity of the non-inverting input from 0.5 礧 up to 1.5 礧 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 礧).
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)
