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 MΩ.

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. When supplied in the lead (Pb) free package, the device is

RoHS compliant.
