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.

INL and DNL are measured at V

DNL specification limits of

1 LSB maximum are guaranteed monotonic operating conditions. See Figure 28 test circuit.

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.
