Description
The TSL260R, TSL261R, and TSL262R are infrared light-to-voltage optical sensors, each combining a
photodiode and a transimpedance amplifier (feedback resistor = 16 M
Ω, 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.
