AD5220–SPECIFICATIONS
Typicals 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 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.
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 band-
width. The highest R value results in the minimum overall power consumption.
All dynamic characteristics use V
See timing diagrams for location of measured values. All input control voltages are specified with t
of 1.6 V. Switching characteristics are measured using both V
