1 Typicals 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 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.
