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.
The maximum current in each code is defined by IAW = (V
The terms, resistor performance mode and R-Perf mode, are used interchangeably. See the Resistor Performance Mode section.
Guaranteed by design and not subject to production test.
See Figure 24 for more details.
Resistor Terminal A and Resistor Terminal W have no limitations on polarity with respect to each other. Dual-supply operation enables ground referenced bipolar
signal adjustment.
Different from operating current, the supply current for the fuse program lasts approximately 55 ms.
Different from operating current, the supply current for the fuse read lasts approximately 500 ns.
