• Differential non-linearity error

Differential non-linearity error refers to the difference between 1-LSB width based on the theoretical A-

D conversion characteristics (an analog input width that can meet the expectation of outputting an

equal code) and an actually measured 1-LSB width (analog input voltage width that outputs an equal

code). If 10-bit resolution is used and if VREF (reference voltage) = 5.12 V, “differential non-linearity

error =

± 1LSB” refers to the fact that 1-LSB width actually measured falls on a range from 0 mV to 10

mV though 1-LSB width based on the theoretical A-D conversion characteristics is 5 mV.
