NOTES: A. This curve is based on the assumption that Vref+ and Vref– have been adjusted so that the voltage at the transition from digital 0 to
1 (VZT) is 2.44 mV, and the transition to full scale (VFT) is 4.9898 V, 1 LSB = 4.88 mV.
B. The full scale value (VFS) is the step whose nominal midstep value has the highest absolute value. The zero-scale value (VZS) is
the step whose nominal midstep value equals zero.
