(1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Recommended Operating Conditions indicate conditions for which the device is intended to be functional, but specific performance is not ensured. For ensured specifications and the test conditions, see the Electrical Characteristics: 2.7 V tables.
(2) The maximum power dissipation must be derated at elevated temperatures and is dictated by TJ(MAX), θJA, and the ambient temperature, TA. The maximum allowable power dissipation PDMAX = (TJ(MAX) - TA)/ θJA or the number given in Absolute Maximum Ratings, whichever is lower.
(3) 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 assurance of parametric performance is indicated in the electrical tables under conditions of internal self-heating where TJ> TA.
(4) Typical values represent the most likely parametric norm 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 specified on shipped production material.
(5) All limits are specified by testing, design, or statistical analysis.
(6) Offset voltage temperature drift is determined by dividing the change in VOS at the temperature extremes by the total temperature change.
(7) The number specified is the average of rising and falling slew rates and measured at 90% to 10%.
(8) This parameter is specified by design and/or characterization and is not tested in production.
(9) Positive Bias Current corresponds to current flowing into the device.
