EQUATION 6-1:
Equation 6-2
determine the resistance between the wiper and
terminal B.
EQUATION 6-2:
The digital potentiometer is available in four nominal
resistances (R
defined as the resistance between terminal A and
terminal B. The four nominal resistances are 5 kΩ,
10 kΩ, 50 kΩ, and 100 kΩ.
The total resistance of the device has minimal variation
due to operating voltage (see
