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. The maximum current in each code is defined by I
(see Figure 20).
Guaranteed by design and not subject to production test.
Common-mode leakage current is a measure of the dc leakage from any Terminal B, or 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.
