Parameters Sym Min Typ Max Units 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: See Figure 2-6 and Figure 2-7 for temperature effects. 3: The ISC specifications are for design guidance only; they are not tested. |
