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.

NOTES: 3. Measurements are made with RL = 10 kΩ between output and ground.
4. Optical measurements are made using small-angle incident radiation from an LED optical source.
5. The 640 nm input irradiance Ee is supplied by an AlInGaP LED with peak wavelength λp = 640 nm.
6. Irradiance responsivity is characterized over the range VO = 0.2 to 4 V. The best-fit straight line of Output Voltage VO versus
irradiance Ee over this range may have a positive or negative extrapolated VO value for Ee = 0. For low irradiance values, the output
voltage VO versus irradiance Ee characteristic is non linear with a deviation toward VO = 0, Ee = 0 origin from the best-fit straight
line referenced above.
