1 Typicals represent average readings at 25°C, 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. See Test Circuits.
3 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. See Figure 37.
4 Resistor Terminal A, Resistor Terminal B, and Resistor Terminal W have no limitations on polarity with respect to each other.
5 Guaranteed by design, not subject to production test.
6 PDISS is calculated from (IDD × VDD). CMOS logic level inputs result in minimum power dissipation.
7 Bandwidth, noise, and settling time are dependent on the terminal resistance value chosen. The lowest R value results in the fastest settling time and highest
bandwidth. The highest R value results in the minimum overall power consumption.
8 All dynamic characteristics use VDD = 5 V.
9 See timing diagram in Figure 3 for location of measured values.
