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. (2) All limits are ensured 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) Offset voltage temperature drift determined by dividing the change in VOS at temperature extremes into the total temperature change. (5) Positive current corresponds to current flowing into the device. (6) 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. Short circuit test is a momentary test. Output short circuit duration is infinite for VS ≤ 6V at room temperature and below. For VS > 6V, allowable short circuit duration is 1.5 ms. (7) Slew rate is the slower of the rising and falling slew rates. Connected as a Voltage Follower.
