Description
The TSL12S, TSL13S, and TSL14S are cost-optimized, highly integrated light-to-voltage optical sensors, each
combining a photodiode and a transimpedance amplifier (feedback resistor = 80 MΩ, 20 MΩ, and 5 MΩ,
respectively) on a single monolithic integrated circuit. The photodiode active area is 0.5 mm
×
0.5 mm and the
sensors respond to light in the range of 320 nm to 1050 nm. Output voltage is linear with light intensity
(irradiance) incident on the sensor over a wide dynamic range. These devices are supplied in a 3-lead clear
plastic sidelooker package (S). When supplied in the lead (Pb) free package, the device is RoHS compliant.
