(1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for
which the device is intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test
conditions, see the Electrical Characteristics.
(2) Human body model, 1.5 kΩ in series with 100 pF.
(3) Limiting input pin current is only necessary for input voltages that exceed absolute maximum input voltage rating.
(4) Applies to both single-supply and split-supply operation. Continuous short circuit operation at elevated ambient temperature can result in
exceeding the maximum allowed junction temperature of 150°C. Output currents in excess of ±30 mA over long term may adversely
affect reliability.
(5) Do not short circuit output to V+, when V+ is greater than 12V or reliability will be adversely affected.

(1) Typical values represent the most likely parametric norm.
(2) All limits are guaranteed by testing or statistical analysis.
(3) Input offset voltage average drift is calculated by dividing the accelerated operating life V

drift by the equivalent operational time. This
represents worst case input conditions and includes the first 30 days of drift.
