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 ...

Those twisty knobs connected to potentiometers aren’t necessarily a strict linear progression from one resistance to another. Potentiometers have a taper. Yes, sometimes it’s a linear taper that’s a ...

Catalyst Semiconductor’s CAT5116 is a new Digitally Programmable Potentiometer (DPP™) integrated circuit (IC) for the audio and optical equipment markets. The CAT5116 features a 100-tap, log-taper ...

Small, resilient and easy to use, digital potentiometers are becoming widely accepted as replacements for mechanical potentiometers, especially in volume-control applications. In this type of audio ...

[Stephen Woodward] is familiar with digital potentiometers but is also familiar with their limitations. That spurred him to create the PWMPot which performs a similar function, but with better ...
