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
maximum 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 T_J(Max), θ_JA, and T_A. The maximum allowable power dissipation at any ambient temperature is P_D = (T_J(Max)
− T_A) /θ_JA.
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 by testing or statistical analysis.
Note 7: V⁺ = 15V, V_CM = 7.5V and R_L connected to 7.5V. For Sourcing tests, 7.5V ≤ V_O ≤ 11.5V. For Sinking tests, 2.5V ≤ V_O ≤ 7.5V.
Note 8: V⁺ = 15V. Connected as Voltage Follower with 10V step input. Number specified is the slower of the positive and negative slew rates.
Note 9: Input referred V⁺ = 15V and R_L = 100 kΩ connected to 7.5V. Each amp excited in turm with 1 kHz to produce V_O = 12 V_PP.
Note 10: For operating at elevated temperatures the device must be derated based on the thermal resistance θ_JA with P_D = (T_J − T_A)/θ_JA. All numbers apply for pack-
ages soldered directly into a PC board.
Note 11: Do not connect output to V⁺, when V⁺ is greater than 13V or reliability will be adversely affected.
Note 12: All numbers apply for packages soldered directly into a PC board.
