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.
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.
