Resistor position nonlinearity error R-INL is the deviation from an ideal value measured between the maximum and minimum resistance wiper positions. R-DNL
measures the relative step change from an ideal value measured between successive tap positions. Parts are guaranteed monotonic.
3
Pb-free parts have a 35 ppm/°C temperature coefficient (tempco).

INL and DNL are measured at V

Resistor Terminals A, B, and W have no limitations on polarity with respect to each other.

Bandwidth, noise, and settling times 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.
