description
The TSL250, TSL251, and TSL252 are light-to-voltage optical sensors, each combining a photodiode and a
transimpedance amplifier (feedback resistor = 16 MΩ, 8 MΩ, and 2 MΩ respectively) on a single monolithic IC.
The output voltage is directly proportional to the light intensity (irradiance) on the photodiode. These devices
utilize Texas Instruments silicon-gate LinCMOS™ technology, which provides improved amplifier offset-voltage
stability and low power consumption.

† _{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.
