Typicals 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
−1 LSB minimum are guaranteed monotonic operating conditions (see Figure 26).
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 Terminal B and Terminal W to a common-mode bias level of V
EEMEM restore mode current is not continuous. Current is consumed while EEMEM locations are read and transferred to the RDAC register (see Figure 22). To
minimize power dissipation, a NOP instruction should be issued immediately after Instruction 1 (0x1).
Power dissipation is calculated by P
