(1) All limits are specified by testing or statistical analysis.
(2) Typical values represent the most likely parametric normal.
(3) V⁺ = 15 V. Connected as voltage follower with 10-V step input. Number specified is the slower of either the positive or negative slew
rates.
(4) Input referred, V⁺ = 15 V and R_L = 100 kΩ connected to 7.5 V. Each amplifier excited in turn with 1 kHz to produce V_O = 12 V_PP.
