Resolution: Analog change that can be identified by an A/D converter
Integral linearity error: Deviation of the straight line connecting the zero transition point ("0000 0000 0000" <--> "0000 0000 0001")
and full-scale transition point ("1111 1111 1110" <--> "1111 1111 1111") from actual conversion characteristics
includes zero transition error, full-scale transition error, and non linearity error.
Differential linearity error: Deviation from the ideal value of the input voltage required for changing the output code by 1 LSB
Total error: Difference between the actual value and the theoretical value. The total error
