Note 1: 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 2: Human Body Model is 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. Boldface
limits apply at the temperature extremes.
