EL400C
200MHz Current Feedback Amplifier
Printed Circuit Layout
As with any high frequency device, good PCB layout is
necessary for optimum performance. Ground plane con-
struction is a requirement, as is good power-supply and
Offset Adjust bypassing close to the package. The
inverting input is sensitive to stray capacitance, there-
fore connections at the inverting input should be
minimal, close to the package, and constructed with as
little coupling the ground plane as possible.
Capacitance at the output node will reduce stability,
eventually resulting in peaking, and finally oscillation if
the capacitance is large enough. The design of the
EL400C allows a larger capacitive load than comparable
products, yet there are occasions when a series resistor
before the capacitance may be needed. Please refer to
the graphs to determine the proper resistor value needed.
