NOTES
1
Typicals represent average readings at +25°C and V
DD
= +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 Figure 29 test circuit.
3
INL 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
= V
DD
and V
B
= 0 V.
DNL specification limits of
±
1 LSB maximum are guaranteed monotonic operating conditions. See Figure 28 test circuit.
4
Resistor terminals A, B, W have no limitations on polarity with respect to each other.
5
Guaranteed by design and not subject to production test.

P
DISS
is calculated from (I
DD
×
V
DD
). 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 band-
width. The highest R value results in the minimum overall power consumption.
8
All dynamic characteristics use V
DD
= +5 V.
9
See timing diagrams for location of measured values. All input control voltages are specified with t
R

F
= 1 ns (10% to 90% of V
DD
) and timed from a voltage level
of 1.6 V. Switching characteristics are measured using both V
