Description
The TSL237 light-to-frequency converter combines a silicon photodiode and a current-to-frequency converter
on a single monolithic CMOS integrated circuit. Output is a square wave (50% duty cycle) with frequency directly
proportional to light intensity (irradiance) on the photodiode. The digital output allows direct interface to a
microcontroller or other logic circuitry. The device has been temperature compensated for the
ultraviolet-to-visible light range of 320 nm to 700 nm and responds over the light range of 320 nm to 1050 nm.
The TSL237 is characterized for operation over the temperature range of 40癈 to 85癈 and is supplied in a
3-lead clear plastic side-looker package with an integral lens. When supplied in the lead (Pb) free package, the
device is RoHS compliant.
For automotive and other extended temperature applications, please contact TAOS for information.
