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 the ideal position between successive tap positions. Parts are guaranteed monotonic. See the test circuit in Figure 28.

B
= 0 V. DNL specification limits
of ±1 LSB maximum are guaranteed monotonic at operating conditions. See the test circuit in Figure 27.

Resistor Terminal A, Terminal B, and Wiper W have no limitations on polarity with respect to each other.
7
Guaranteed by design and not subject to production test.
8
Measured at the Ax terminals. All Ax terminals are open circuited in shutdown mode.

P
DISS
is calculated from (I
DD

). CMOS logic level inputs result in minimum power dissipation.

See the timing diagrams (Figure 3 to Figure 5) for the location of the measured values. All input control voltages are specified with t
R
= t
F
= 2.5 ns (10% to 90% of 3 V)
and timed from a voltage level of 1.5 V. Switching characteristics are measured using both V
