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.

(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.
