Digitally adjustable potentiometers, also known as digital potentiometers, or digpots, are replacing the old-fashioned mechanical versions in all electronic systems, not just in the more well-known audio applications. A simpler and less expensive version of the digital-to-analog converter (DAC), digital pots produce an analog output in the form of a variable resistance. Available in volatile and nonvolatile types, the digital approach has many advantages. Digital pots are insensitive to dust, dirt, and moisture, which can kill a mechanical part if they intrude.
