(1) Specified by characterization only.
(2) At high supply voltage, placing the OPAx992 in a sudden short to mid-supply or ground will lead to rapid thermal shutdown.  Output current greater than ISC can be achieved if rapid thermal shutdown is avoided as per Output Voltage Swing vs Output Current.
(3) See Slew Rate vs Input Step Voltage for more information.
