NOTES:

13. AV = -10.

14. Load Capacitance should be less than 10pF. Turn on time delay

typically 4ns.

15. It is recommended that resistors be carbon composition and the

feedback and summing network ratios be matched to 0.1%.

16. SETTLE POINT (Summing Node) capacitance should be less

than 10pF. For optimum settling time results, it is recommended

that the test circuit be constructed directly onto the device pins. A

Tektronix 568 Sampling Oscilloscope with S-3A sampling heads is

recommended as a settle point monitor.
