(1) All limits are specified by testing or statistical analysis.
(2) Typical Values indicate the most likely parametric norm as determined at the time of characterization. Actual typical values may vary
over time and will also depend on the application and configuration. The typical values are not tested and are not ensured on shipped
production material.
(3) The offset voltage average drift is determined by dividing the value of V
OS
at the temperature extremes by the total temperature change.
