NOTES:
12. A_V = -10.
13. Load Capacitance should be less than 10pF.
14. It is recommended that resistors be carbon composition
and that feedback and summing network ratios be
matched to 0.1%.
15. SETTLING 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 recommend-
ed as a settle point monitor.
