(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 each trigger was generated 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.
