Description
The TSL238 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. Output enable (OE
) places the output in a high-impedance state for
multiple-unit sharing of a microcontroller input line. 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 TSL238 is characterized for operation over the temperature range of 40癈 to 85癈 and is supplied in an
8-lead plastic small outline package. 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.
