5V Electrical Characteristics (continued)
Unless otherwise specified, all limits ensured for at T_J = 25°C, V⁺ = 5V, V^− = 0V, V_O = V_CM = V⁺/2, and R_L = 100Ω to V⁺/2, R_F
= 510Ω. Boldface limits apply at the temperature extremes.

(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) Short circuit test is a momentary test. See next note.
(7) 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.
(8) Positive current corresponds to current flowing into the device.
