(5) Full-scale error
(6) Differential linearity error
This shows the difference between the actual measurement value of the analog input voltage and the
theoretical value (full-scale value − 3/2 LSB) when the digital output changes from 1……110 to 1……111.
While the ideal width of code output is 1 LSB, this indicates the difference between the actual measurement
value and the ideal value.
This indicates the basic characteristics of the A/D conversion when the voltage applied to the analog input pins
of the same channel is consistently increased bit by bit from AV
when the input voltage is increased or decreased, or when two or more channels are used.
