Rheostat position non-linearity R-INL is the deviation from an ideal value measured between the maximum resistance and the minimum
resistance wiper positions. R-DNL measures the relative step change from the ideal between successive tap positions. I
V
INL and DNL are measured at V
specification limits of ±1 LSB max are specified monotonic operating conditions. See Figure 2-25 for test circuit.
Resistor terminals A,B and W have no restrictions on polarity with respect to each other. Full-scale and zero-scale error were measured
using Figure 2-25.
Measured at V
Supply current is independent of current through the potentiometers.
