±5V Electrical Characteristics (continued)
Unless otherwise specified, all limits guaranteed for at T_J = 25°C, V⁺ = 5V, V^− = −5V, V_CM = V_O, and R_L = 100Ω (or as
specified) tied to 0V. Boldface limits apply at the temperature extremes.

Miscellaneous Performance
(3) Slew rate is the "worst case" of the rising and falling slew rates.
(4) Drift determined by dividing the change in parameter at temperature extremes by the total temperature change.
(5) Positive current corresponds to current flowing into the device.
