9.1.5.3 Glossary
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

N: A/D converter digital output value.
VZT(Ideal value) = AVRL + 0.5LSB[V]
VFST(Ideal value) = AVRH - 1.5LSB[V]
VNT: Voltage at which the digital output changes from "(N – 1)" to "N".
