TSL245R Datasheet (TAOS) - INFRARED LIGHT-TO-FREQUENCY CONVERTER

TSL245R, INFRARED LIGHT-TO-FREQUENCY CONVERTER

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.
