D
(Q)
(max) is the value guaranteed with all programming fuses blown (maximum programming code set). The D

programming ranges.
6
Step size is larger than required, in order to provide for manufacturing spread. See Characteristic Definitions section.
7
Non-ideal behavior in the programming D-to-A converter (DAC) can cause the step size at each significant bit rollover code to be greater than twice
