摘要： 此应用程序说明的目的是显示如何可以再生 DS1847/48 数字电阻标定常数。本应用指南假定读者熟悉编程条 DS1847 或 DS1848 的数据单的查找表。本应用指南将描述所需，测量，以及显示所需重新生成标定常数的计算。最后，此应用程序的说明将显示一个示例电子表格计算器 （它的链接可以找到此应用程序注月底），可以用于执行计算，一旦被输入几个测量。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……
