3V Electrical Characteristics (continued)
Unless otherwise specified, all limits ensured for at T_J = 25°C, V⁺ = 3V, V^− = 0V, V_O = V_CM = V⁺/2, and R_L = 2kΩ to V⁺/2.
Boldface limits apply at the temperature extremes.

(3) Slew rate is the average of the rising and falling slew rates.
(4) Offset voltage average drift determined by dividing the change in V_OS at temperature extremes into the total temperature change.
(5) Positive current corresponds to current flowing into the device.
(6) f ≤ 1kHz (see typical performance Characteristics)
(7) Short circuit test is a momentary test.
(8) Positive current corresponds to current flowing into the device.
