TSL257 - High-Sensitivity Light-to-Voltage Converter - 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. The output voltage is directly proportional to light intensity (irradiance) on the photodiode. The TSL257 has a transimpedance gain of 320 Megohm. 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. The TSL257T is supplied in a compact 4-lead surface mount package.
