Electrical Characteristics (continued)
Unless otherwise specified, all limits ensured for T_A = T_J = 25°C. Boldface limits apply at the temperature extremes. V⁺ = 5V,
V^− = 0V, V_CM = 1.5V, V_O = V⁺/2 and R_L > 1M unless otherwise specified.

(1) Typical values represent the most likely parametric norm.
(2) All limits are ensured at room temperature (standard type face) or at operating temperature extremes (bold face type).
(3) V⁺ = 15V. Connected as Voltage Follower with 10V step input. Number specified is the slower of the positive and negative slew rates.
(4) Input referred V⁺ = 15V and R_L = 100 kΩ connected to V⁺/2. Each amp excited in turn with 100 Hz to produce V_O = 12 V_PP.
