6.5 ±5V Electrical Characteristics
Unless otherwise specified, all limits ensured for V⁺ = +5V, V^− = −5V, V_CM = 0V, A_V = +1, R_F = 25Ω for gain = +1, R_F = 402Ω
for gain ≥ +2, and R_L = 100Ω. Boldface limits apply at the temperature extremes.

(1) All limits are specified by testing or statistical analysis.
(2) Typical Values represent the most likely parametric norm.
(3) Slew rate is the slower of the rising and falling slew rates. Slew rate is rate of change from 10% to 90% of output voltage step.
(4) Offset voltage average drift is determined by dividing the change in V_OS at temperature extremes into the total temperature change.
