1 Typical values 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 and minimum resistance wiper positions. R-DNL is the
relative step change from an ideal value measured between successive tap positions. Parts are guaranteed monotonic, except R-DNL of AD5252 1 kΩ version at VDD =
2.7 V, IW = VDD/R for both VDD = 3 V and VDD = 5 V.
3 INL and DNL are measured at V
W with the RDAC configured as a potentiometer divider, similar to a voltage output digital-to-analog converter. VA = VDD and VB = 0 V.
DNL specification limits of ±1 LSB maximum are guaranteed monotonic operating conditions.
4 Resistor Terminal A, Terminal B, and Terminal W have no limitations on polarity with respect to each other.
5 Guaranteed by design and not subject to production test.
6 Command 0 NOP should be activated after Command 1 to minimize I
DD_READ current consumption.
7 P
DISS is calculated from IDD × VDD = 5 V.
8 All dynamic characteristics use V
DD = 5 V.
