Resistor position nonlinearity error 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 ideal between successive tap positions. Parts are guaranteed monotonic. See the test circuit in Figure 38.

INL and DNL are measured at V
DNL specification limits of ±1 LSB maximum are guaranteed monotonic operating conditions. See the test circuit in
Resistor Terminal A, Resistor Terminal B, and Resistor Terminal W have no limitations on polarity with respect to each other.
Guaranteed by design and not subject to production test. Resistor-terminal capacitance tests are measured with 2.5 V bias on the measured terminal. The remaining
resistor terminals are left open circuit.
Measured at the Ax terminals. All Ax terminals are open-circuited in shutdown mode.
Worst-case supply current is consumed when the input logic level is at 2.4 V, a standard characteristic of CMOS logic. See
