Definition of A/D Converter Terms
Resolution : Analog variation that is recognized by an A/D converter.
Linearity error : Zero transition point (00 0000 0000
←→
00 0000 0001) and full-scale transition point.
Difference between the line connected (11 1111 1110
←→
11 1111 1111) and actual conversion character-
istics.
Differential linearity error : Deviation of input voltage, that is required for changing output code by 1 LSB, from
an ideal value.
Total error : This error indicates the difference between actual and ideal values, including the zero transition
error/full-scale transition error/linearity error.
