Description
The TSL250R, TSL251R, and TSL252R are light-to-voltage optical sensors, each combining a photodiode and
a transimpedance amplifier (feedback resistor = 16 M
Ω
, 8 M
Ω
, and 2.8 M
Ω
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.
