摘要：本应用笔记的目的是展示如何DS1847/48数字电阻校准常数可以再生。本应用笔记假定读者熟悉的编程DS1847或DS1848数据表的查找表节。本应用笔记将介绍所需的测量，以及需要重新校准常数的计算。最后，本应用笔记将显示例如电子表格计算器（可以在本应用笔记中发现一个链接） ，可以用来执行计算多次测量一次输入。Maxim > App Notes > A/D and D/A CONVERSION/SAMPLING CIRCUITS DIGITAL POTENTIOMETERS FIBER-OPTIC CIRCUITS POWER-SUPPLY CIRCUITS Keywords: digital resistor, digital pot, digital potentiometer, digipot, DS1847, DS1848, potentiometers Mar 10, 2003 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 of all, this application note……
