R-INL is the deviation from an ideal value measured between RWB at Code 0x00B to Code 0x3FF or between RWA at Code 0x3F3 to Code 0x000. 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 The terms resistor performance mode and R-perf mode are used interchangeably. 4 Guaranteed by design; not subject to production test. 5 INL and DNL are measured at VW 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 The A, B, and W resistor terminals have no limitations on polarity with respect to each other. Dual-supply operation enables ground-referenced bipolar signal adjustment. 7 PDISS is calculated from (IDD × VDD) + (ISS × VSS) + (ILOGIC × VLOGIC). 8 All dynamic characteristics use VDD = +15 V, VSS = −15 V, and VLOGIC = 5 V.
