1
Measurements made after the selected input range has been calibrated.
2
The offset error in the signal near zero analog input is not corrected, and is not included in the accuracy specifications.
3
There is a channel-to-channel carryover conversion error, due to the finite settling time of the analog multiplexer. The
maximum carryover error is 0.1% of the difference between channels.
4
Mean accuracy includes effects of non-linearity and drift from 0 to 55 degrees C.
