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.
3. The device may be hand soldered provided that heat is applied only to the solder pad and no contact is made between the tip of
the solder iron and the device lead. The maximum time heat should be applied to the device is 5 seconds.

NOTES:
4. Measurements are made with R
L
= 10 k
Ω
between output and ground.
5. Optical measurements are made using small-angle incident radiation from an LED optical source.
6. The 640 nm input irradiance E
e
is supplied by an Al
I
nGaP LED with peak wavelength
λ
p
= 640 nm.
7. The 940 nm input irradiance E
e
is supplied by a GaAs LED with peak wavelength
λ
p
= 940 nm.
8. Irradiance responsivity is characterized over the range V
O
= V
D
to 3 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.
9. 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.
