DC Electrical Characteristics (continued)
Unless otherwise specified, all limits ensured for T_J = 25°C. Boldface limits apply at the temperature extremes. V⁺ = 5V, V^− =
0V, V_CM = 1.5V, V_O = 2.5V and R_L > 1M unless otherwise specified.

(1) Typical values represent the most likely parametric norm. Limits are specified by testing or correlation.
(2) V⁺ = 15V. Connected as Voltage Follower with 10V step input. Number specified is the slower of the positive and negative slew rates.
(3) Input referred. V⁺ = 15V and R_L = 10 kΩ connected to V⁺/2. Each amp excited in turn with 1 kHz to produce V_O = 13 V_PP.
