NOTES
1
Typicals represent average readings at 25
°
C, V
= 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 posi-
tions. R-DNL measures the relative step change from ideal between successive tap positions. Parts are guaranteed monotonic. See Figure 10 test circuit.
3
INL and DNL are measured at V
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 9 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.
6
P
is calculated from (I
×
V
). 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
= 5 V.
9
See timing diagram for location of measured values.
