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 Test Circuits.
INL and DNL are measured at V
specification limits of ±1 LSB maximum are guaranteed monotonic operating conditions. See Figure 37.
Resistor Terminal A, Resistor Terminal B, and Resistor Terminal W have no limitations on polarity with respect to each other.
Guaranteed by design, not subject to production test.
P
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
bandwidth. The highest R value results in the minimum overall power consumption.
All dynamic characteristics use V
See timing diagram in Figure 3 for location of measured values.
