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 TJ = TA. No ensured specification of parametric performance is indicated in the electrical

tables under conditions of internal self heating where TJ > TA. 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.

(4)

Connected as voltage follower with input step from V− to V+. Number specified is the slower of the positive and negative slew rates.
