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.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. All voltages are with respect to GND.
2. Output may be shorted to supply.

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