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 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 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)
