The use of Xicor’s nonvolatile digital potentiometers (XDCPs) in mixed signal applications can offer a number of unique system advantages over the use of mechanical potentiometers. During prototyping, a design engineer may want to evaluate these devices in order to see how well they will perform in the intended application. In many cases, a simple circuit to control an XDCPs operation (and which can be “jumpered” into a target system) is sufficient. To that end, this application note features some simple circuit schematics that an engineer can build in order to quickly evaluate any of Xicor’s XDCPs.
