(1)

Typical Values represent the most likely parametric norm.

(2)

V+ = 5V. Connected as voltage follower with 5V step input. Number specified is the slower of the positive and negative slew rates.

(3)

Input referred, V+ = 5V and RL = 100kΩ connected to 2.5V. Each amp excited in turn with 1kHz to produce VO = 3VPP.
