CIRCUIT CONFIGURATIONS
Figure 60 through Figure 66 show typical schematics for the
AD8099 in various gain configurations. Table 4 data was
collected using the schematics shown in Figure 60 through
Figure 66. Resistor R1, as shown in Figure 60 through Figure 66,
is the test equipment termination resistor. R1 is not required for
normal operation, but is shown in the schematics for
completeness.
