2线控制的数字DIP开关使用的DS3904

资料介绍
摘要: DS3904包含三个数字控制的非易失性(NV )可变电阻器。它的每个可变电阻器置于高阻抗状态的能力。使用此功能,它有可能创造一个2线DIP开关控制非易失数字。本应用笔记将解释要创建一个数字化的DIP开关使用的DS3904电阻设置,以及如何创建NV输出,可用于配置数字系统。

APPLICATION NOTE 238
2-Wire Controlled Digital DIP Switch Using the DS3904

Abstract: The DS3904 contains three digitally controlled nonvolatile (NV) variable resistors. It has the capability
of placing each of the variable resistors into a high-impedance state. Using this feature, it is possible to create a
2-wire controlled NV digital DIP switch. This application note will explain the resistor settings necessary to
create a digital DIP switch using the DS3904, and how to create NV outputs that can be used to configure
digital systems.
