2.7V Electrical Characteristics (continued)
Unless otherwise specified, all limits ensured for TA = 25°C, V+ = 2.7V, Vâ = 0V, VCM = V+/2. Boldface limits apply at the
temperature extremes.

(1) All limits are ensured by testing or statistical analysis.
(2) Typical Values represent the most likely parametric norm.
(3) Input offset voltage Average Drift is calculated by dividing the accelerated operating life drift average by the equivalent operational time.
The input offset voltage average drift represents the input offset voltage change at worst-case input conditions.
(4) Do not short circuit output to V+, when V+ is > 12V or reliability will be adversely affected.
