NOTES:
14. AV = -10.
15. Load Capacitance should be less than 10pF.
16. It is recommended that resistors be carbon composition and that
feedback and summing network ratios be matched to 0.1%.
17. 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.
