NOTES:

11. AV = -2.

12. Feedback and summing resistors must be matched (0.1%).

13. HP5082-2810 clipping diodes recommended.

14. Tektronix P6201 FET probe used at settling point.

15. For 0.01% settling time, heat sinking is suggested to reduce

thermal effects and an analog ground plane with supply

decoupling is suggested to minimize ground loop errors.
