(3) Quantization error
(4) Zero-scale error
This is an error of ±1/2 LSB that inevitably occurs when an analog value is converted into a digital value. Because
the A/D converter converts analog input voltages in a range of ±1/2 LSB into the same digital codes, a quantization
error is unavoidable.
This error is not included in the overall error, zero-scale error, full-scale error, integral linearity error, or differential
linearity error in the characteristics table.
This is the difference between the actually measured analog input voltage and its theoretical value when the digital
output changes from 0…000 to 0…001 (1/2 LSB).
