FAQ on Analog Device’s digital Potentiometers. App note here.
A digiPOT is a digitally controlled resistor that changes the impedance between the terminals and wiper depending on the code loaded in the RDAC register. Digital potentiometers avoid the problems that mechanical potentiometers face, such as physical size and wear and tear, as well as sensitivity to vibration, temperature, and humidity.
