TSL257T, HIGH-SENSITIVITY LIGHT-TO-VOLTAGE CONVERTER

The TSL257T is a high-sensitivity low-noise light-to-voltage optical converter that combines a photodiode and a transimpedance amplifier on a single monolithic CMOS integrated circuit.

Output voltage is directly proportional to light intensity (irradiance) on the photodiode.

The TSL257T has a transi
