Notice: Stresses above those listed under “Absolute
Maximum Ratings” may cause permanent damage to the
device. This is a stress rating only and functional operation of
the device at those or any other conditions above those
indicated in the operational listings of this specification is not
implied. Exposure to maximum rating conditions for extended
periods may affect device reliability.

Note 1:
Describes the offset (under the specified conditions) right after power-up, or just after the CAL/CS pin is toggled. Thus,
1/f noise effects (an apparent wander in VOS; see Figure 2-35) are not included. 2:

The ISC specifications are for design guidance only; they are not tested.
