Data Sheet
five feedforward capacitor input pins, all capacitor inputs may
be used only if the user intends to drive large variations of DUT
load capacitances. If the DUT load capacitance is known and
doesn’t change for all combinations of voltage ranges and test
conditions, then it is possible only one set of CCx and CFx is
required.
REQUIRED EXTERNAL COMPONENTS
The minimum required external components are shown in the
block diagram in Figure 60. Decoupling is very dependent on
the type of supplies used, the board layout, and the noise in the
system. It is possible that less decoupling may be required as a
result. Although there are four compensation input pins and
