1 Typical specifications represent average readings at 25°C, VDD = 5 V, and VSS = 0 V.  
2 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.  
3 The maximum current in each code is defined by IAW = (VDD − 1)/RAW  
.
4 The terms, resistor performance mode and R-Perf mode, are used interchangeably. See the Resistor Performance Mode section.  
5 Guaranteed by design and not subject to production test.  
6 See Figure 24 for more details.  
7 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.  
8 Different from operating current, the supply current for the fuse program lasts approximately 55 ms.  
9 Different from operating current, the supply current for the fuse read lasts approximately 500 ns.
