Accuracy is defined as the error between the measured and reference output voltages, tabulated in the Conversion Table at the

specified conditions of supply gain setting, voltage, and temperature (expressed in °C). Accuracy limits include line regulation within the

specified conditions. Accuracy limits do not include load regulation; they assume no DC load.

Output Accuracy

These limits do not include DC load regulation. These stated accuracy limits are with reference to the values in Table 1.
