TSL12S, TSL13S,
TSL14S
Light-to-Voltage Converters
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 = 80M, 20M, and 5M, respectively) on a
single monolithic integrated circuit. The photodiode active area
is 0.5mm × 0.5mm and the sensors respond to light in the range
of 320nm to 1050nm. 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).
Ordering Information and Content Guide appear at end of
datasheet.

TSL12S, TSL13S, TSL14S − Electrical Characteristics
Note(s):
1. Measurements are made with RL = 10k between output and ground.
2. Optical measurements are made using small-angle incident radiation from an LED optical source.
3. The 640nm input irradiance Ee is supplied by an AlInGaP LED with peak wavelength λp = 640nm.
4. Irradiance responsivity is characterized over the range VO = 0.2 to 4V. 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.
