This shows the difference between the actual measurement value of the analog input voltage and the theoretical
value (Full-scale − 3/2LSB) when the digital output changes from 1......110 to 1......111.
This shows the degree to which the conversion characteristics deviate from the ideal linear relationship. It expresses
the maximum value of the difference between the actual measurement value and the ideal straight line when the zero-
scale error and full-scale error are 0.
While the ideal width of code output is 1LSB, this indicates the difference between the actual measurement value and
the ideal value.
This expresses the time from the start of sampling to when the digital output is obtained.
The sampling time is included in the conversion time in the characteristics table.
This is the time the analog switch is turned on for the analog voltage to be sampled by the sample & hold circuit.
