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 RL = 100 kΩ connected to 7.5 V. Each amplifier excited in turn with 1 kHz to produce VO = 12 VPP.
