(1) Typical Values represent the most likely parametric norm.
(2) All limits are specified by testing or statistical analysis.
(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 7.5V. Each amp excited in turn with 1 kHz to produce V_O = 12 V_PP.
