† 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.

NOTES: 3. Measurements are made with RL = 10 kΩ between output and ground.

4. Optical measurements are made using small-angle incident radiation from an LED optical source.

5. The input irradiance Ee is supplied by an AlInGaP LED with peak wavelength λp = 635 nm

6. The temperature coefficient of output voltage measurement is made by adjusting irradiance such that VO is approximately 2 V at

25°C and then with irradiance held constant, measuring VO while varying the temperature between 0°C and 70°C.

7. Irradiance responsivity is characterized over the range VO = 0.05 to 2.9 V. The best-fit straight line of Output Voltage VO versus

irradiance Ee over this range will typically have a positive extrapolated VO value for Ee = 0.
