Description

The TSL245R 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 TSL245R is characterized for operation over the temperature range

of −25°C to 70°C and is supplied in a 3-lead plastic side-looker package with an integral visible-light cutoff filter

and lens. When supplied in the lead (Pb) free package, the devices are RoHS compliant.
