A/D Converter Glossary
Resolution : Analog changes that are identifiable with the A/D converter
Linearity error : 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 1 LSB from the
theoretical value
Total error : The total error is defined as a difference between the actual value and the theoretical value, which
includes zero-transition error/full-scale transition error and linearity error.
