One difference between digital potentiometers and
mechanical potentiometers is the wiper resistance. The
wiper resistance (R
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
nected between the ideal wiper and wiper terminal of
the digital potentiometer.
