X refers to package designator, R or N.
External capacitor selection must be as described in Figure 5.

Total Output Error includes Offset and Gain Error. Total Output Error and Offset Error are with respect to the Full-Scale Output and are measured with an ideal
+5 V reference. If the internal reference is used, the reference errors must be added to the Offset and Total Output Errors.
4
PSRR is measured by varying V
CC
from 12 V to its maximum 32 V.
