1 Typical represents 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. See the test circuit in Figure 38.
IW = 50 μA for VDD = 3 V and IW = 400 μA for VDD = 5 V for the 10 kΩ versions.
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. See the test circuit in Figure 37.
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. Resistor-terminal capacitance tests are measured with 2.5 V bias on the measured terminal. The remaining
resistor terminals are left open circuit.
7 Measured at the Ax terminals. All Ax terminals are open-circuited in shutdown mode.
8 Worst-case supply current is consumed when the input logic level is at 2.4 V, a standard characteristic of CMOS logic. See Figure 28 for a plot of IDD vs. logic voltage.
9 PDISS is calculated from (IDD × VDD). CMOS logic level inputs result in minimum power dissipation.
10 All dynamic characteristics use VDD = 5 V.
11 Measured at a VW pin where an adjacent VW pin is making a full-scale voltage change.
