1 Typical represents the average reading 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, except R-DNL of AD5252 1 kΩ
version at VDD = 2.7 V, IW = VDD/R for both VDD = 3 V or VDD = 5 V.
3 INL and DNL are measured at VW with the RDAC configured as a potentiometer divider similar to a voltage output D/A converter. VA = VDD and VB = 0 V. DNL
specification limits of ±1 LSB maximum are guaranteed monotonic operating conditions.
4 Resistor Terminals A, B, and W have no limitations on polarity with respect to each other.
5 Guaranteed by design and not subject to production test.
6 cmd 0 NOP should be activated after cmd 1 to minimize IDD_READ current consumption.
7 PDISS is calculated from IDD × VDD = 5 V.
8 All dynamic characteristics use VDD = 5 V.
