Typical values represent average readings at 25°C and V
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. I

V
INL and DNL are measured at V
DNL specification limits of ±1 LSB maximum are guaranteed monotonic operating conditions.
Resistor Terminal A, Terminal B, and Terminal W have no limitations on polarity with respect to each other.
Guaranteed by design and not subject to production test.
Measured at the Ax terminals. All Ax terminals are open-circuit in shutdown mode.
Worst-case supply current consumed when all logic-input levels set at 2.4 V, which is the standard characteristic of CMOS logic.

Switching characteristics are measured using V
All dynamic characteristics use V
Measured at V
See Figure 5 for location of measured values. All input control voltages are specified with t
