−1 LSB minimum are guaranteed monotonic operating condition (see Figure 27).
Typical values represent average readings at 25°C and V
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. I
R
INL and DNL are measured at V
Resistor Terminal A, Resistor Terminal B, and Resistor Terminal W have no limitations on polarity with respect to each other. Dual-supply operation enables ground-
referenced bipolar signal adjustment.
Guaranteed by design and not subject to production test.
Common-mode leakage current is a measure of the dc leakage from any Terminal B–W to a common-mode bias level of V
EEMEM restore mode current is not continuous. Current consumed while EEMEM locations are read and transferred to the RDAC register (see Figure 23). To minimize

power dissipation, a NOP Instruction 0 (0x0) should be issued immediately after Instruction 1 (0x1).
