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 specific performance is not guaranteed. For guaranteed specifications and the test conditions, see the Electrical Characteristics.
Note 2: Human body model, 1.5 kΩ in series with 100 pF.
Note 3: 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 4: 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 5: Typical Values represent the most likely parametric norm.
Note 6: All limits are guaranteed by testing or statistical analysis.
Note 7: V⁺ = 2.7V, V_CM = 1.35V and R_L connected to 1.35V. For Sourcing tests, 1.35V ≤ V_O ≤ 2.7V. For Sinking tests, 0.5V ≤ V_O ≤ 1.35V.
Note 8: Connected as Voltage Follower with 1.0V step input. Number specified is the slower of the positive and negative slew rates. Input referred, V⁺ = 2.7V and
R_L = 100 kΩ connected to 1.35V. Amp excited with 1 kHz to produce V_O = 1 V_PP.
Note 9: Bias Current guaranteed by design and processing.
3V DC Electrical Characteristics
Unless otherwise specified, all limits guaranteed for T_J = 25˚C, V⁺ = 3V, V^− = 0V, V_CM = V_O = V⁺/2 and R_L > 1 MΩ. Bold-
face limits apply at the temperature extremes.
