1
Typicals represent average readings at 25°C and VDD = 5 V.
2
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 IWB = (VDD 1)/RWB.
3
Guaranteed by design and not subject to production test.
4
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 VDD/2.
5
EEMEM restore mode current is not continuous. Current is consumed while EEMEM locations are read and transferred to the RDAC register.
6
PDISS is calculated from (IDD × VDD) + (ISS × VSS).
7
All dynamic characteristics use VDD = +2.5 V and VSS = 2.5 V.
