Potentiometers, or variable resistors, are a standard component that we take for granted. If it says “10k log” on a volume pot, than we fit and forget. But if like [Ben Holmes] you are modelling ...

Digital potentiometers (dpots) are ubiquitous components available in a variety of packages, resistances, and resolutions. However, few implement anything but the usual linear function of resistance ...

Catalyst Semiconductor’s CAT5116 is a new Digitally Programmable Potentiometer (DPP) integrated circuit (IC) for the audio and optical equipment markets. Catalyst Semiconductor’s CAT5116 is a new ...

Winbond Electronics, based in HsinChu, Taiwan, is a relatively new supplier to the digital potentiometer market. Their first offering, the WMS720x ICs, are “set and lock” devices targeted at ...

Adjusting the volume dial on a sound system, sensing your finger position on a touch screen, and knowing when someone’s in the car are just a few examples of where you encounter variable resistors in ...

You can use digital potentiometers to create easy to use, adjustable signal chains replacing mechanical potentiometers, thus improving specifications, reliability and PCB area. Design details on how ...
