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. IWB = (VDD − 1)/RWB (see Figure 27).
3 INL and DNL are measured at VW with the RDAC configured as a potentiometer divider similar to a voltage output DAC. VA = VDD and VB = VSS. DNL specification limits of
±1 LSB maximum are guaranteed monotonic operating conditions (see Figure 28).
4 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.
5 Guaranteed by design and not subject to production test.
6 Common-mode leakage current is a measure of the dc leakage from any Terminal A, Terminal B, or Terminal W to a common-mode bias level of VDD/2.
7 EEMEM restore mode current is not continuous. Current is consumed while EEMEM locations are read and transferred to the RDAC register.
8 PDISS is calculated from (IDD × VDD) + (ISS × VSS).
9 All dynamic characteristics use VDD = +2.5 V and VSS = −2.5 V.
