The TSL257T is a high-sensitivity low-noise light-to-voltage optical converter that combines a photodiode and

G s 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 transimpedance gain of

A t 320 MΩ. The device has improved offset voltage stability and low power consumption and is supplied in a
compact 4-lead surface-mount package.
