AC Electrical Characteristics (Continued)
Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is in-
tended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. 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 maxi-
mum allowed junction temperature of 150˚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)–TA)/θJA.
Note 4: Limits are guaranteed by testing or correlation.
Note 5: V+ = 15V, VCM = 7.5V and RL connected to 7.5V. For sourcing tests, 7.5V ≤ VO ≤ 11.5V. For sinking tests, 2.5V ≤ VO ≤ 7.5V.
Note 6: V+ = 15V. Connected as Voltage Follower with 10V step input. Number specified is the slower of the positive and negative slew rates.
Note 7: For operating at elevated temperatures the device must be derated based on the thermal resistance
θJA with PD = (TJ–TA)/θJA.
Note 8: All numbers apply for packages soldered directly into a PC board.
Note 9: Do not connect output to V+ when V+ is greater than 13V or reliability may be adversely affected.
