(1) Limits are ensured to AOQL (Average Outgoing Quality Level).
(2) 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.
