APPLICATIO S I FOR ATIO

The effect of this input dynamic current can be analyzed
using the test circuit of Figure 16. The CPAR capacitor
includes the LTC2410 pin capacitance (5pF typical) plus
the capacitance of the test fixture used to obtain the results
shown in Figures 17 and 18. A careful implementation can
bring the total input capacitance (CIN + CPAR) closer to 5pF
thus achieving better performance than the one predicted
by Figures 17 and 18. For simplicity, two distinct situa-
tions can be considered.
