APPLICATION NOTE 233
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
