description

The TSL260, TSL261, and TSL262 are light-to-voltage optical sensors each combining a photodiode and a

transimpedance amplifier (feedback resistor = 16 M

Ω, 8 MΩ, and 2 MΩ, respectively) on a single monolithic

integrated circuit. The output voltage is directly proportional to the infrared light intensity (irradiance) on the

photodiode. The TSL260, TSL261, and TSL262 utilize Texas Instruments silicon-gate LinCMOS

™ technology,

which provides good amplifier offset-voltage stability and low power consumption.

mechanical data

The photodiode/amplifier chip is packaged in a black, infrared-transmissive plastic package. The integrated

photodiode active area is typically 1,0 mm2 (0.0016 in2), 0.5 mm2 (0.00078 in2), and 0.26 mm2 (0.0004 in2) for

the TSL260, TSL261, and TSL262, respectively.
