Description

The TSL235 light-to-frequency converter combines a silicon photodiode and a current-to-frequency converter

on a single monolithic CMOS integrated circuit. The output is a square wave (50% duty cycle) with frequency

directly proportional to light intensity. Because it is TTL compatible, the 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 300 nm to 700 nm and responds over the light range of 300 nm to 1100 nm. The TSL235

is characterized for operation over the temperature range of –25°C to 70°C.

†

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and

functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not

implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTE 1: All voltage values are with respect to GND.
