(7) Integral linearity error
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.
(8) Conversion time
This expresses the time from when the analog input voltage was applied to the time when the digital output
was obtained.
The sampling time is included in the conversion time in the characteristics table.
(9) Sampling time
This is the time the analog switch is turned on for the analog voltage to be sampled by the sample & hold
circuit.
