Note 1:Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating conditions indicate conditions for which the deviceis intended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the ElectricalCharacteristics. The guaranteed specifications apply only for the test conditions listed. Note 2: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 110˚C. Output currents in excess of±30 mA over long term may adversely affect reliability. Note 3:The maximum power dissipation is a function of TJ(max),θJA, and TA. The maximum allowable power dissipation at any ambient temperature is PD = (TJ(max) −T A)/θJA. Note 4:Human body model, 1.5 kΩ in series with 100 pF. Note 5:Typical Values represent the most likely parametric norm. Note 6:All limits are guaranteed at room temperature (standard type face) or at operating temperature extremes (bold face type). Note 8:V+ = 15V. Connected as Voltage Follower with 10V step input. Number specified in the slower of the positive and negative slew rates. Note 9:For operating at elevated temperatures the device must be derated based on the thermal resistanceθJA with PD = (TJ −T A)/θJA. Note 10:All numbers apply for packages soldered directly into a PC board. Note 11:Do not connect output to V+ when V+ is greater than 13V or reliability may be adversely affected.
