Digital Potentiometers

Digital potentiometers (digipots) are used to trim and scale analog signals. They provide an output resistance that is variable based on digital inputs and so are sometimes referred to as resistive digital-to-analog converters (RDACs).

Digipots are typically available with linear or logarithmic tap points. In addition, Maxim offers some further variations of the basic digipot. Nonvolatile digipots retain their last programmed wiper position when the power supply is switched off. OTP digpots set the wiper's power-on reset (POR) position to a user-defined value.
