1 Typical specifications 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 the ideal between successive tap positions. Parts are guaranteed monotonic.  
3 VA = VDD, VB = 0 V, wiper (VW) = no connect.  
4 Specifications apply to all VRs.  
5 INL and DNL are measured at VW with the RDAC configured as a potentiometer divider similar to a voltage output digital-to-analog converter (DAC). VA = VDD and VB = 0 V.  
DNL specification limits of 1 LSB maximum are guaranteed monotonic operating conditions.  
6 Resistor Terminal A, Resistor Terminal B, and Resistor Terminal W have no limitations on polarity with respect to each other.  
7 Guaranteed by design, but not subject to production test.  
8 Measured at the A terminal. The A terminal is open circuited in shutdown mode.  
9 PDISS is calculated from (IDD × VDD). CMOS logic level inputs result in minimum power dissipation.  
10 All dynamic characteristics use VDD = 5 V.
