Output voltage is directly proportional to the light intensity (irradiance) on the photodiode. The device has improved amplifier offset-voltage stability and low power consumption and is supplied in a 3-lead clear plastic sidelooker package with an integral lens. When supplied in the lead (Pb) free package, the device is RoHS compliant.

Measurements are made with RL = 10 kΩ between output and ground. Optical measurements are made using small-angle incident radiation from an LED optical source. The input irradiance Ee is supplied by an AlInGaP LED with peak wavelength λp = 635 nm 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.
