VFT = VFS – 1/2 LSB
VFS
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 0.0024 V and the transition to full scale (VFT) is 4.908 V. 1 LSB = 4.8 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.
