Typicals represent average readings at 25 C, V
Resistor position nonlinearity error R-INL is the deviation from an ideal value measured between the maximum resistance and the minimum resistance wiper positions.
Wiper resistance is not measured on the R
INL and DNL are measured at V
Resistor Terminals A, B, W have no limitations on polarity with respect to each other.
Guaranteed by design and 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.
All dynamic characteristics use V
See timing diagram for location of measured values. All input control voltages are specified with t
R-DNL measures the relative step change from ideal between successive tap positions. Parts are guaranteed monotonic. See Figure 22 test circuit.
specification limits of 1 LSB maximum are guaranteed monotonic operating conditions. See Figure 21 test circuit.
The highest R value results in the minimum overall power consumption.
