Conditions

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.

See Figure 2-6 and Figure 2-7 for temperature effects.

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