5V AC Electrical Characteristics
Unless otherwise specified, all limits guaranteed for T_J = 25˚C, V⁺ = 5V, V^− = 0V, V_CM = V_O = V⁺/2 and R_L > 1 MΩ. Bold-
face limits apply at the temperature extremes.

Note 10: 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 guaranteed. For guaranteed specifications and the test conditions, see the Electrical Characteristics.
Note 11: Human body model, 1.5 kΩ in series with 100 pF.
Note 12: 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 at 150˚C.
Note 13: 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. All numbers apply for packages soldered directly into a PC board.
Note 14: Typical Values represent the most likely parametric norm.
Note 15: All limits are guaranteed by testing or statistical analysis.
Note 16: V⁺ = 5V, V_CM = 2.5V and R_L connected to 2.5V. For Sourcing tests, 2.5V ≤ V_O ≤ 5.0V. For Sinking tests, 0.5V ≤ V_O ≤ 2.5V.
Note 17: Connected as Voltage Follower with 1.0V step input. Number specified is the slower of the positive slew rate. The negative slew rate is faster. Input referred,
V⁺ = 5V and R_L = 100 kΩ connected to 1.5V. Amp excited with 1 kHz to produce V_O = 1 V_PP.
Note 18: Bias Current guaranteed by design and processing.
10V DC Electrical Characteristics
Unless otherwise specified, all limits guaranteed for T_J = 25˚C, V⁺ = 10V, V^− = 0V, V_CM = V_O = V⁺/2 and R_L > 1 MΩ. Bold-
