Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES:
1. All voltages are with respect to GND.
2. Output may be shorted to supply.

between output and ground.
4. Optical measurements are made using small-angle incident radiation from an LED optical source.
5. The input irradiance E
e
is supplied by an Al
I
nGaP LED with peak wavelength
λ
p
= 635 nm
6. The temperature coefficient of output voltage measurement is made by adjusting irradiance such that V
O
is approximately 2 V at
25
°
C and then with irradiance held constant, measuring V
O
while varying the temperature between 0
°
C and 70
°
C.
7. Irradiance responsivity is characterized over the range V
O
= 0.05 to 2.9 V. The best-fit straight line of Output Voltage V
O
versus
irradiance E
e
over this range will typically have a positive extrapolated V
O
value for E
e
= 0.
