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.

Due to its pseudo-logarithmic behavior, this circuit provides over three decades of gain through the 64 gain settings of the Xicor dual 64-tap potentiometer (Fig. 2).
