R-DNL measures the relative step change from ideal between successive tap positions. Parts are guaranteed monotonic. See Test Circuits. 3INL and DNL are measured at V W with the RDAC configured as a potentiometer divider similar to a voltage output D/A converter. V A = VDD and VB = 0 V. DNL specification limits of ±1 LSB maximum are guaranteed monotonic operating conditions. See Figure 10. 4Resistor terminals A, B, W have no limitations on polarity with respect to each other. 5Guaranteed by design and not subject to production test. 6P DISS is calculated from (IDD × V DD). CMOS logic level inputs result in minimum power dissipation. 7Bandwidth, noise, and settling time are dependent on the terminal resistance value chosen. The lowest R value results in the fastest settling time and highest band- width. The highest R value results in the minimum overall power consumption. 8All dynamic characteristics use V DD = 5 V. 9See timing diagram for location of measured values.
