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.
