• 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.
