Electrical Characteristics (Continued)

Note 9: The limits found in the following table supersede the limits shown in the Electrical Characteristics Table. The Accuracy specification includes errors due to

linearity, offset and gain. The accuracy specification includes effects of self heating with negligible digital output loading. Pull-up resistors should be maximized (10k

typical recommended), so that self heating due to digital output loading is negligible.
