† 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.
NOTE 1: All voltages are with respect to GND.


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 MW, and 1 MW respectively) on a single monolithic IC. Output voltage is directly proportional to the light intensity (irradiance) on the photodiode. The TSL254 use silicon-gate CMOS technology that provides improved amplifier offset-voltage stability and low power consumption.
