† 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.

NOTE 1: All voltages are with respect to GND.

NOTES: 2. Measured with RL = 10 kΩ between output and ground.

3. Optical measurements are made using small-angle incident radiation from a light-emitting diode (LED) optical source.

4. The input irradiance is supplied by a GaAs light-emitting diode with the following characteristics: peak wavelength λp = 940 nm.

5. Irradiance responsivity is characterized over the range VO = 0.1 V to 4.5 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.

6. Power supply rejection ratio PSRR is defined as 20 log (ΔVDD(f)/ΔVO(f)) with VDD(f = 0) = 5 V and VO(f = 0) = 2 V.
