TSL252

Description

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.
