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.
