NOTES
1Typicals represent average readings at 25
°C, V
DD = 5 V.
2Resistor 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 22 test circuit.
3Wiper resistance is not measured on the R
AB = 1 M models.
4INL 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 = VDD and VB = 0 V. DNL
specification limits of
±1 LSB maximum are guaranteed monotonic operating conditions. See Figure 21 test circuit.
5Resistor Terminals A, B, W have no limitations on polarity with respect to each other.
6Guaranteed by design and not subject to production test.
7P
DISS is calculated from (IDD × V DD). CMOS logic level inputs result in minimum power dissipation.
8Bandwidth, noise and settling time are dependent on the terminal resistance value chosen. The lowest R value results in the fastest settling time and highest bandwidth.
The highest R value results in the minimum overall power consumption.
9All dynamic characteristics use V
DD = 5 V.
10See timing diagram for location of measured values. All input control voltages are specified with t
R = tF = 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 VDD = 5 V or VDD = 3 V.
Specifications subject to change without notice.
