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:
Increment between adjacent VOS trim points; Figure 2-3 shows how this affects the VOS repeatability.
3:
See Figure 2-6 and Figure 2-7 for temperature effects.
4:
The ISC specifications are for design guidance only; they are not tested.
