Description
The TSL257 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 TSL257 has a transimpedance gain of 320 M
.
The device has improved offset voltage stability and low power consumption and is supplied in a 3-lead clear
plastic sidelooker package with an integral lens.
