Linearity error
(Continued)
: Analog changes that are identifiable by the A/D converter.
: The deviation of the straight line connecting the zero transition point
(00 0000 0000
←→
00 0000 0001) with the full-scale transition point
(11 1111 1110
←→
11 1111 1111) from actual conversion characteristics.
Differential linearity error : The deviation of input voltage needed to change the output code by one LSB
from the theoretical value.
Total error
: The difference between actual and theoretical conversion values including a
zero transition/full-scale transition/linearity error.
