1 Typical values represent average readings at 25°C, VDD = 5 V, VSS = 0 V, and VLOGIC = 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. The maximum wiper current is limited to 0.75 × VDD/RAB.
3 Guaranteed by design and characterization, not subject to production test.
4 INL and DNL are measured at VWB with the RDAC configured as a potentiometer divider similar to a voltage output DAC. VA = VDD and VB = 0 V. DNL specification limits
of ±1 LSB maximum are guaranteed monotonic operating conditions.
5 Resistor Terminal A, Resistor Terminal B, and Resistor Terminal W have no limitations on polarity with respect to each other.
6 Different from operating current; supply current for NVM program lasts approximately 30 ms.
7 Different from operating current; supply current for NVM read lasts approximately 20 μs.
8 PDISS is calculated from (IDD × VDD) + (ILOGIC × VLOGIC).
9 All dynamic characteristics use VDD = 5.5 V, and VLOGIC = 5 V.
10 Endurance is qualified at 100,000 cycles per JEDEC Standard 22, Method A117 and measured at 150°C.
11 Retention lifetime equivalent at junction temperature (TJ) = 125°C per JEDEC Standard 22, Method A117. Retention lifetime based on an activation energy of 1 eV
derates with junction temperature in the Flash/EE memory.
