INTERFACE TIMING CHARACTERISTICS (ALL PARTS)
Guaranteed by design, not subject to production test. See Figure 23 for location of measured values. All input control voltages are specified
with tR = tF = 2.5 ns (10% to 90% of 3 V) and timed from a voltage level of 1.5 V. Switching characteristics are measured using both
VDD = 3 V and 5 V. When the part is not in operation, the SDA and SCL pins should be pulled high. When these pins are pulled low, the
I2C interface at these pins conducts current of about 0.8 mA at VDD = 5.5 V and 0.2 mA at VDD = 2.7 V.

1 Typical values represent average readings at 25°C and 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, except R-DNL of AD5254 1 kΩ
version at VDD = 2.7V, IW = VDD/R for both VDD = 3 V or VDD = 5 V.
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. DNL
specification limits of ±1 LSB maximum are guaranteed monotonic operating conditions.
4 Resistor terminals A, B, and W have no limitations on polarity with respect to each other.
5 Guaranteed by design and not subject to production test.
6 cmd 0 NOP should be activated after cmd 1 in order to minimize IDD_RESTORE current consumption.
7 PDISS is calculated from (IDD × VDD = 5 V).
8 All dynamic characteristics use VDD = 5 V.
9 During power-up, all outputs preset to midscale before restoring EEMEM contents. RDAC0 has the shortest whereas RDAC3 has the longest EEMEM restore time.
10 Delay time after power-on or RESET before new EEMEM data to be written.
11 Endurance is qualified to 100,000 cycles per JEDEC Std. 22 method A117, and is measured at –40°C, +25°C, and +85°C; typical endurance at +25°C is 700,000 cycles.
12 Retention lifetime equivalent at junction temperature (TJ) = 55°C per JEDEC Std. 22, Method A117. Retention lifetime based on an activation energy of 0.6eV derates
with junction temperature.
