Typical values represent 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.

All limits are specified by testing or statistical analysis.

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.
(2)
All limits are specified by testing or statistical analysis.
(3)
Do not short circuit the output to V+ when V+ is greater than 12V or reliability will be adversely affected.
(4)
Input offset voltage average drift is calculated by dividing the accelerated operating life VOS drift by the equivalent operational time. This
represents worst case input conditions and includes the first 30 days of drift.
