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 ...

Trimmer potentiometers are ubiquitous components and are available in a variety of packages, resolutions, and temperature stabilities. However, none of these potentiometers implements anything but the ...

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 ...

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 ...

The circuit shown is a differential amplifier that not only offers programmability but also provides a logarithmic-type gain (Fig. 1). The traditional gain-setting resistors of the amplifier, R1 and ...
