Light-to-Voltage Optical Sensors
General 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.
