Regenerating the DS1847/DS1848 Resistor Calibration Constants

Abstract: The purpose of this application note is to show how the DS1847/48 digital resistor calibration constants can be regenerated. This application note assumes that the reader is familiar with the Programming the Lookup Table section of the DS1847 or DS1848 data sheets. This application note will describe the measurements required, as well as show the calculations needed to regenerate the calibration constants. Last of all, this application note will show an example spreadsheet calculator (a link to it can be found at the end of this application note) that can be used to perform the calculations once several measurements are input
