description
The TSL253 and TSL254 are light-to-voltage optical converters, each combining a 1-mm-square photodiode
and a transimpedance amplifier (feedback resistor = 16 M
, and 1 M 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.
