Typicals represent average readings at 25°C,V
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.
±1% resistor tolerance code range; R
V
INL and DNL are measured at V
±1 LSB maximum are guaranteed monotonic operating conditions.
Resistor Terminals A, B, and W have no limitations on polarity with respect to each other. Dual-supply operation enables ground-referenced bipolar signal adjustment.
Guaranteed by design and not subject to production test.
Different from operating current; supply current for fuse read lasts approximately TBDµs..
