TSL260R, TSL261R, TSL262R Infrared Light-to-Voltage Optical Sensors The TSL260R, TSL261R, and TSL262R are infrared General Description light-to-voltage optical sensors, each combining a photodiode and a transimpedance amplifier (feedback resistor = 16 M, 8 M, and 2.8 M 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. When supplied in the lead (Pb) free package, the device is RoHS compliant. Ordering Information and Content Guide appear at end of datasheet.
