linearity, offset, and gain error using single-end supplies
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 attempts to drive the output to a negative voltage. However, because the most negative
supply rail is ground, the output cannot drive below ground and clamps the output at 0 V.
The output voltage remains at zero until the input code value produces a sufficient positive output voltage to
overcome the negative offset voltage, resulting in the transfer function shown in Figure 25.

Figure 25. Effect of Negative Offset (Single Supply)
This offset error, not the linearity error, produces this breakpoint. The transfer function would have followed the
dotted line if the output buffer could drive below the ground rail.
