Wiper Resistance

One difference between digital potentiometers and

mechanical potentiometers is the wiper resistance. The

wiper resistance (R

) is a result of the interconnecting

materials on the IC between the internal resistive ele-

ments and the wiper pin. This can be modeled by using

an ideal potentiometer, with a resistance of R

con-

nected between the ideal wiper and wiper terminal of

the digital potentiometer.
