Description

The TSL260R, TSL261R, and TSL262R are infrared 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 plastic sidelooker package with an integral visible light cutoff filter and lens.
