7_{VOUT(Q)(max) is the value available with all programming fuses blown (maximum programming code set). VOUT(Q) is the total range from VOUT(Q)init up to and includ-}
ing V_OUT(Q)(max). See Characteristic Definitions.
8_{Step size is larger than required to account for manufacturing spread. See Characteristics Definitions}
9_{Non-ideal behavior in the programming DAC can cause the step size at each significant bit rollover code to be twice the maximum specified value of StepVOUT(Q) or}
