Description
The TSL260R, TSL261R, and TSL262R are infrared light-to-voltage optical sensors, each combining a
photodiode and a transimpedance amplifier (feedback resistor = 16 MΩ, 8 MΩ, and 2.8 MΩ respectively) on a
single monolithic IC. Output voltage is directly proportional to the light intensity (irradiance) on the photodiode.
These devices have improved amplifier offset-voltage stability and low power consumption and are supplied
in a 3-lead plastic sidelooker package with an integral visible light cutoff filter and lens.

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 RL = 10 kΩ between output and ground.
Optical measurements are made using small-angle incident radiation from an LED optical source.
The input irradiance Ee is supplied by a GaAs LED with peak wavelength λp = 940 nm
Irradiance responsivity is characterized over the range VO = 0.05 to 2.9 V. The best-fit straight line of Output Voltage VO versus
irradiance Ee over this range will typically have a positive extrapolated VO value for Ee = 0.
