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 the 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 Guaranteed by design and not subject to production test.
5 See Figure 8 for more details.
6 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.
7 Different from operating current; the supply current for the fuse program lasts approximately 55 ms.
8 Different from operating current; the supply current for the fuse read lasts approximately 500 ns.
9 PDISS is calculated from (IDD × VDD) + (ISS × VSS).
10 All dynamic characteristics use VDD = +2.5 V, VSS = 2.5 V.
INTERFACE TIMING SPECIFICATIONS
VDD = 2.7 V to 5.5 V; all specifications TMIN to TMAX, unless otherwise noted.
