e 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.

6. The input irradiance Ee is supplied by a GaAlAs LED with peak wavelength λp = 880 nm
a n 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.
