2.7V Electrical Characteristics (continued)
Unless otherwise specified, all limits guaranteed for at T_J = 25°C, V⁺ = 2.7V, V^− = 0V, V_CM = V_O = V⁺/2, and R_f = 2kΩ, and R_L
= 1kΩ to V⁺/2. Boldface limits apply at the temperature extremes.

(7) Short circuit test is a momentary test.
(8) Output short circuit duration is infinite for V_S < 6V at room temperature and below. For V_S > 6V, allowable short circuit duration is 1.5ms.
5V Electrical Characteristics
Unless otherwise specified, all limits guaranteed for at T_J = 25°C, V⁺ = 5V, V^− = 0V, V_CM = V_O = V⁺/2, and R_f = 2kΩ, and R_L =
1kΩ to V⁺/2. Boldface limits apply at the temperature extremes.

(1) All limits are guaranteed by testing or statistical analysis.
(2) Typical values represent the most likely parametric norm.
(3) Slew rate is the average of the rising and falling slew rates.
(4) Guaranteed based on characterization only.
(5) Positive current corresponds to current flowing into the device.
(6) Offset voltage average drift determined by dividing the change in V_OS at temperature extremes into the total temperature change.
