Description
The TSL250RD, TSL251RD, TSL260RD, and TSL261RD are light-to-voltage optical sensors, each combining
a photodiode and a transimpedance amplifier on a single monolithic IC. The TSL250RD and TSL260RD have
an equivalent feedback resistance of 16 MΩ and a photodiode measuring 1 square mm. The TSL251RD and
TSL261RD have an equivalent feedback resistance of 8 MΩ and a photodiode measuring 0.5 square mm.
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.
