AC Electrical Characteristics (Continued)
Unless otherwise specified, all limits guaranteed for T_J = 25˚C, V⁺ = 5V, V^− = 0V, V_CM = V_O = V⁺/2. Boldface limits apply at
the temperature extreme.

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 of 150˚C. Output currents in excess of ±30 mA over long term may adversely affect reliability.
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: Limiting input pin current is only necessary for input voltages that exceed absolute maximum input voltage rating.
Note 8: Do not short circuit output to V+, when V+ is greater than 12V or reliability will be adversely affected.
Note 9: C_L includes the probe and jig capacitance.
Note 10: Input offset voltage average drift is calculated by dividing the accelerated operating life V_OS drift by the equivalent operational time. This represents worst
case input conditions and includes the first 30 days of drift.
Note 11: Input step voltage for propagation delay measurement is 2V.
