NOTES:

19. Load Capacitance should be less than 10pF.

20. It is recommended that resistors be carbon composition and

that feedback and summing network ratios be matched to 0.1%.

21. 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 recommended as a settle point monitor.
