NOTES
1Input offset voltage specifications are guaranteed after 5 minutes at TA = +25°C.
2Full power bandwidth = slew rate/2 π VPEAK. Refer to Figure 1.
All min and max specifications are guaranteed. Specifications in boldface are tested on all production units at final electrical test. All others are guaranteed but not necessarily tested.
Specifications subject to change without notice.
