(5) 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 45mA over long term may adversely affect
reliability.

(1) Electrical Table values apply only for factory testing conditions at the temperature indicated. Factory testing conditions result in very
limited self-heating of the device such that T
J
= T
A
. No ensured specification of parametric performance is indicated in the electrical
tables under conditions of internal self heating where T
J
> T
A
. See Application Note section for information on temperature derating of
this device. Absolute Maximum Ratings indicated junction temperature limits beyond which the device may be permanently degraded,
either mechanically or electrically.
(2) All limits are specified by testing or statistical analysis.
(3) 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.
