1 Typical values represent average readings at 25°C, VDD = 15 V, VSS = 15 V, and VLOGIC = 5 V.
2 Resistor position nonlinearity error. R-INL is the deviation from an ideal value measured between the RWB at code 0x02 to code 0xFF or between RWA at code 0xFD to
code 0x00. R-DNL measures the relative step change from ideal between successive tap positions. The specification is guaranteed in resistor performance mode, with
a wiper current of 1 mA for VA < 12 V and 1.2 mA for VA ≥ 12 V.
3 Resistor performance mode (see the Resistor Performance Mode section). The terms resistor performance mode and R-Perf mode are used interchangeably.
4 Guaranteed by design and characterization, not subject to production test.
5 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.
6 Resistor Terminal A, Resistor Terminal B, and Resistor Terminal W have no limitations on polarity with respect to each other. Dual-supply operation enables ground-
referenced bipolar signal adjustment.
7 Different from operating current; supply current for fuse program lasts approximately 550 μs.
8 Different from operating current; supply current for fuse read lasts approximately 550 μs.
9 PDISS is calculated from (IDD × VDD) + (ISS × VSS) + (ILOGIC × VLOGIC).
10 All dynamic characteristics use VDD = 15 V, VSS = 15 V, and VLOGIC = 5 V.
