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 digital-to-analog converter (DAC). VA = VDD and VB =
0 V. DNL specification limits of ±1 LSB maximum are guaranteed monotonic operating conditions.
5 Resistor Terminal A, Resistor Terminal B, and Resistor Terminal W have no limitations on polarity with respect to each other.
6 Guaranteed by design and not subject to production test.
7 PDISS is calculated from (IDD × VDD). CMOS logic level inputs result in minimum power dissipation.
8 All dynamic characteristics use VDD = 5 V.
