1 Typicals represent average readings at 25°C, VDD = 5 V.
2 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.
3 INL and DNL are measured at VW with the RDAC configured as a potentiometer divider similar to a voltage output D/A converter. VA = VDD and VB = 0 V.
4 Guaranteed by design and not subject to production test.
5 DNL specification limits of ±1 LSB maximum are guaranteed monotonic operating conditions.
6 Resistor Terminals A, B, and W have no limitations on polarity with respect to each other.
7
PU and PD have 100 kΩ internal pull-up resistors, IDD_ACT = VDD/100 kΩ + IOSC (internal oscillator operating current) when PU or PD is connected to ground.
8 PDISS is calculated based on IDD_STBY × VDD only. IDD_ACT duration should be short. Users should not hold PU or PD pin to ground longer than necessary to elevate power
dissipation.
9 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.
10 All dynamic characteristics use VDD = 5 V.
11 Note that all input control voltages are specified with tR = tF = 1 ns (10% to 90% of VDD) and timed from a voltage level of 1.6 V. Switching characteristics are measured
using VDD = 5 V.
12 The debouncer keeps monitoring the logic-low level once PU is connected to ground. Once the signal lasts longer than 11 ms, the debouncer assumes the last
bounce is met and allows the AD5228 to increment by one step. If the PU signal remains at low and reaches tAS_START, the AD5528 increments again, see Figure 7. Similar
characteristics apply to PD operation.
