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 ...

If an accurate, stable, high resolution digital pot with a logarithmic taper (log of resistance proportional to setting) were available, it would be easy to arrange a gain-control circuit that ...

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 ...

How Potentiometer Resistance Changes Linear vs logarithmic taper potentiometer graph Potentiometers can have a linear range of resistances or a logarithmic range.

The SPI port controls the potentiometer setpoints. Multiple devices can be daisy chained together without taking up additional port pins on the host controller. This makes it possible, for example, to ...

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 ...
