Data Sheet
Chapter 10 Definition of terms
(3) Quantization error
This is the error of ±1/2 LSB that always occurs when an analog value is
converted into a digital value. Because the A/D converter converts an analog
input voltage in a range of ±1/2 LSB into the same digital code, the
quantization error is unavoidable.
Note that this error is not included in the total error, zero-scale error, full-scale
error, integral linearity error, and differential linearity error in the characteristics
table.
