TSL257-LF Light to Voltage Converter
The TSL257-LF is a high sensitivity low noise light to voltage 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-LF has a transimpedance gain of 320MR. The device has improved the voltage offset and low power consumption.
