Description
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 transimpedance gain of
320 M
Ω
. The device has improved offset voltage stability and low power consumption and is supplied in a
compact 4-lead surface-mount package.
