Resolution
Analog changes that are identifiable with the A/D converter
When the number of bits is 8, analog voltage can be divided into 2
8
= 256.
Linearity error (unit: LSB)
The deviation of the straight line drawn 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
Total error (unit: LSB)
The difference between theoretical and actual conversion values
