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 ideal between successive tap positions. Parts are guaranteed monotonic.  
3 VAB = VDD, wiper (VW) = no connect.  
4 INL and DNL are measured at VW with the RDAC configured as a potentiometer divider similar to a voltage output D/A converter. VA = VDD and VB = 0 V.  
DNL specification limits of 1 LSB maximum are guaranteed monotonic operating conditions.  
5 Resistor Terminals A, B, W have no limitations on polarity with respect to each other.  
6 Guaranteed by design and not subject to production test.  
ꢀ PDISS is calculated from (IDD × VDD). CMOS logic level inputs result in minimum power dissipation.  
8 All dynamic characteristics use VDD = 5 V.
