TSL257 High-Sensitivity Light-to-Voltage Converter
The TSL257 is a high-sensitivity low-noise light-to-voltage
General Description
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 320MΩ. 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. Ordering Information and Content Guide appear at end of datasheet.
