TSL250R, TSL251R, TSL252R Light-to-Voltage Optical Sensors The TSL250R, TSL251R, and TSL252R are light-to-voltage optical General Description sensors, each combining a photodiode and a transimpedance amplifier (feedback resistor = 16M, 8M, and 2.8M 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. Ordering Information and Content Guide appear at end of datasheet.
