3.1.3 Accuracy
Accuracy is represented with respect to the m aximum digital output value.
Accuracy does not change and remains within th e range listed in the performance
specification even if the input character istic is changed by changing offset/gain
settings, input range and resolution mode.
Figure 3.5 shows the range of fluctuation in accuracy when a -1 0 to 10V r a n ge is
selected and in normal resolution mode. Accuracy is ± 0.1% (± 4 digi ts) when the
ambient temperature is 25 ± 5°C, ± 0.3% (± 12 digits) when the ambient temperature is
0 to 55 °C with temperature drift compensation, and ± 0.4% (± 16 digits) when the
ambient temperature is 0 to 55 °C without tem perature drift compensation.
