TSL12S Light-to-Voltage

High sensitivity sidelooker package


The TSL12S, TSL13S, and TSL14S are cost-optimized, highly integrated light-to-voltage optical sensors, each combining a photodiode and a trans-impedance 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.
