 [[ADI>CN0336]] provides robust and complete solution for 4 mA-to-20 mA current to digital conversion with isolation, for wide variety measurements where, sensors with standard 4-20 mA output are used. The design solution is optimized for high precision and low cost measurement, using only three active devices, and has a total unadjusted error of less than 0.1% of full scale range. The accuracy depends on the calibration. [[ADI>CN0336]] provides robust and complete solution for 4 mA-to-20 mA current to digital conversion with isolation, for wide variety measurements where, sensors with standard 4-20 mA output are used.
