(1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings 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 Table.
(2) Human body model, 1.5 kΩ in series with 100 pF. Machine model: 0Ω in series with 100 pF.
(3) Continuous short circuit operation at elevated ambient temperature can result in exceeding the maximum allowed junction temperature at 150°C.
(4) The maximum power dissipation is a function of TJ(MAX), RθJA and TA. The maximum allowable power dissipation at any ambient temperature is PD = (TJ(MAX) − TA)/RθJA. All numbers apply for packages soldered directly onto a PC board.
(5) Typical Values represent the most likely parametric norm.
(6) All limits are specified by testing or statistical analysis.
(7) Offset voltage average drift is determined by dividing the change in VOS at temperature extremes into the total temperature change.
(8) Slew rate is the slower of the rising and falling slew rates. Slew rate is rate of change from 10% to 90% of output voltage step.
