A/D Converter Glossary
Resolution
Analog changes that are identifiable by the A/D converter.
When the number of bits is 8, analog voltage can be divided into 28
= 256.
Linearity error (unit : LSB)
The deviation of the straight line connecting the zero transition point (“0000 0000”
“0000 0001”) with the
full-scale transition point (“1111 1111”
“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.
