The TSL250R, TSL251R, and TSL252R are light-to-voltage optical sensors, each combining a photodiode and
a transimpedance amplifier (feedback resistor = 16 MΩ, 8 MΩ, and 2.8 MΩ respectively) on a single monolithic
IC. Output voltage is directly proportional to the light intensity (irradiance) on the photodiode. These devices
have improved amplifier offset-voltage stability and low power consumption and are supplied in a 3-lead clear
plastic sidelooker package with an integral lens. When supplied in the lead (Pb) free package, the device is
RoHS compliant.

Measurements are made with RL = 10 kΩ between output and ground.
Optical measurements are made using small-angle incident radiation from an LED optical source.
The input irradiance Ee is supplied by an AlInGaP LED with peak wavelength λp = 635 nm
The input irradiance Ee is supplied by a GaAlAs LED with peak wavelength λp = 880 nm
Irradiance responsivity is characterized over the range VO = 0.05 to 2.9 V. The best-fit straight line of Output Voltage VO versus
irradiance Ee over this range will typically have a positive extrapolated VO value for Ee = 0.
