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.

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 GaN/SiC light-emitting diode with the following characteristics: peak wavelength
5. The input irradiance is supplied by an InGaN light-emitting diode with the following characteristics: peak wavelength
6. The input irradiance is supplied by a GaP light-emitting diode with the following characteristics: peak wavelength
7. The input irradiance is supplied by an AlGaAs light-emitting diode with the following characteristics: peak wavelength
8. Irradiance responsivity is characterized over the range V
9. Power supply rejection ratio PSRR is defined as 20 log ( V
