3.4.3 Overall accuracy

3 - 11
The overall accuracy refers to the accuracy relative to the maximum digital output
value.
Even if the I/O characteristic is altered by changing the offset/gain settings, the overall
accuracy does not change but is maintained within the performance range as outlined
in the specification. The overall accuracy of voltage and current input characteristics
are shown in Fig. 3.7 and 3.8.
