• Resolution
• Linearity error
• Differential linearity error
• Total error (unit: LSB)
Analog changes that are identifiable with the A/D converter.
The deviation of the straight line connecting the zero transition point (“00 0000 0000”
the full-scale transition point (“11 1111 1110”
The deviation of input voltage needed to change the output code by 1 LSB from the theoretical value
The difference between theoretical and actual conversion values caused by the zero transition error, full-scale
transition error, linearity error, quantization error, and noise
