A/D Converter Glossary
(Continued)
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.
