NOTES
1
Typicals represent average readings at +25°C and VDD = +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 VB = 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.
6
PDISS is calculated from (I DD × VDD). 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 = tF = 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 DD = +3 V or +5 V.
Specifications subject to change without notice.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. WARNING!
Although the AD5220 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD ESD SENSITIVE DEVICE
precautions are recommended to avoid performance degradation or loss of functionality.
