Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur.
Note 2:
Operating Ratings indicate conditions for which the device is functional, but do not guarantee specific performance limits. For guaranteed specifications and
the test conditions, see the Electrical Characteristics. Datasheet min/max specification limits are guaranteed by design, test, or statistical analysis. The guaranteed
specifications apply only for the test conditions listed. Some performance characteristics may change when the device is not operated under the listed test
conditions.
Note 3:
All voltages are measured with respect to GND, unless otherwise specified.
Note 4:
Linearity Error is the variation in DC gain from V
IN
= 1.0V to 5.0V measured at the points 1.0V, 1.5V, 4.5V, and 5.0V.
