Layout Considerations
T he specified high speed performance of the AD8072 and
AD8073 require careful attention to board layout and compo-
nent selection. Proper RF
design techniques and low parasitic
component selection are mandatory.
T he PCB should have a ground plane covering all unused por-
tions of the component side of the board to provide a low im-
pedance ground path. T he ground plane should be removed
from the area near the input pins to reduce stray capacitance.
Chip capacitors should be used for supply bypassing. One end
of the capacitor should be connected to the ground plane and
the other within 1/8 inches of each power pin. An additional
large (4.7
μ
F–10
μ
F) tantalum electrolytic capacitor should be
connected in parallel, but not necessarily as close to the supply
pins, to provide current for fast large-signal changes at the
device’s output.
T he feedback resistor should be located close to the inverting
input pin in order to keep the stray capacitance at this node to a
minimum. Capacitance variations of less than 1 pF at the invert-
ing input will affect high speed performance.
Stripline design techniques should be used for long signal traces
(greater than about 1 inch). T hese should be designed with a
characteristic impedance of 50
or 75
and be properly termi-
nated at each end.
C rosstalk
Crosstalk between internal amplifiers may vary depending on
which amplifier is being driven and how many amplifiers are
being driven. T his variation typically stems from pin location on
the package and the internal layout of the IC itself. T able I
illustrates the typical crosstalk results for a combination of
conditions.
