Offset
Figure 8. Effect of Negative Offset (Single Power Supply)
This negative offset error, not the linearity error, produces the breakpoint. The transfer function would have
followed the dotted line if the output buffer could be driven to a negative voltage.
For a DAC, linearity is measured between zero input code (all inputs 0) and full scale code (all inputs 1) after
offset and full scale are adjusted out or accounted for in some way. However, single power supply operation does
not allow for adjustment when the offset is negative due to the breakpoint in the transfer function. So the linearity
in the unipolar mode is measured between full scale code and the lowest code which produces a positive output
voltage.
The code is calculated from the maximum specification for the negative offset.
