1 Typical values 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. IW ~ 50 µA @ VDD = 2.7 V and IW ~ 400 µA @ VDD = 5 V for the  
RAB = 10 kΩ version, IW ~ 50 µA for the RAB = 50 kΩ, and IW ~ 25 µA for the RAB = 100 kΩ version (see Figure 26).  
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 minimum are guaranteed monotonic operating condition (see Figure 27).  
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 B–W to a common-mode bias level of VDD/2.  
7 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).  
8 PDISS is calculated from (IDD × VDD) + (ISS × VSS).  
9 All dynamic characteristics use VDD = +2.5 V and VSS = −2.5 V.
