linearity, offset, and gain error
When an amplifier is operated from a single supply, the voltage offset can still be either positive or negative. With
a positive offset, the output voltage changes on the first code change. With a negative offset the output voltage
may not change with the first code depending on the magnitude of the offset voltage.
The output amplifier, with a negative voltage offset, attempts to drive the output to a negative voltage. However,
since the most negative supply rail is ground, the output cannot drive to a negative voltage.
So when the output offset voltage is negative, the output voltage remains at 0 volts until the input code value
produces a sufficient output voltage to overcome the inherent negative offset voltage resulting in the transfer
function shown in Figure 5.

Figure 5. Effect of Negative Offset (Single Supply)
The negative offset error produces a breakpoint, not a linearity error. The transfer function would follow the
dotted line if the output buffer could drive 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 is adjusted out or accounted for in some way. However, single supply operation does not
allow for adjustment when the offset is negative due to the breakpoint in the transfer function. 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.
