Typical values represent average readings at 25°C and V
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 V
2.7 V, I
INL and DNL are measured at V
DNL specification limits of ±1 LSB maximum are guaranteed monotonic operating conditions.
Resistor Terminal A, Terminal B, and Terminal W have no limitations on polarity with respect to each other.
Guaranteed by design and not subject to production test.
Command 0 NOP should be activated after Command 1 to minimize I
