Typicals represent average readings at 25°C; V
Resistor position nonlinearity error. R-INL is the deviation from an ideal value measured between R
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 V
The terms resistor performance mode and R-perf mode are used interchangeably.
Guaranteed by design; not subject to production test.
INL and DNL are measured at V
of ±1 LSB maximum are guaranteed monotonic operating conditions.
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.
