(2) A/D Converter Glossary
Resolution
Analog changes that are identifiable with the A/D converter
When the number of bits is 10, analog voltage can be divided into 210
= 1024.
Linearity error (unit : LSB)
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 1111”
“11 1111 1110”) from actual conversion characteristics
Differential linearity error (unit : LSB)
The deviation of input voltage needed to change the output code by 1 LSB from the theoretical value
Total error (unit : LSB)
The difference between theoretical and actual conversion values
