SY22312-H2 combines a photodiode and a current-to-frequency converter circuit on a single chip.
The output of SY22312-H2 is a square wave (50% duty cycle) with a frequency proportional to the light intensity on the photodiode. This digital output allows for a direct interface to a microcontroller or other logic circuitry. The device has been temperature-compensated for the ultraviolet-to-visible light with wavelengths in the range of 320nm to 700nm, with a peak sensitivity around 600nm.
SY22312-H2 operates at -40°C to 85°C and is available in a compact side-looker package.
