description

The TSL245 infrared 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 the output is TTL compatible, it allows direct interface

to a microcontroller or other logic circuitry. The device responds over the infrared light range of 800 nm to

1100 nm. The TSL245 is characterized for operation over the temperature range of –25°C to 70°C.

The TSL245 is offered in a black, infrared-transmissive package (see Figure 1). The photodiode area is

1.36 mm (0.0029 in ).
