Layout Considerations
The specified high speed performance of the AD8001 requires
careful attention to board layout and component selection.
Proper R
F
design techniques and low parasitic component selec-
tion are mandatory.
The 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. The ground plane should be removed
from the area near the input pins to reduce stray capacitance.
Chip capacitors should be used for supply bypassing (see Figure
49). One end should be connected to the ground plane and the
other within 1/8-inch of each power pin. An additional large
(4.7
μ
F–10
μ
F) tantalum electrolytic capacitor should be con-
nected in parallel, but not necessarily so close, to supply current
for fast, large-signal changes at the output.
The 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 significantly affect high speed performance.
Stripline design techniques should be used for long signal traces
(greater than about 1 in.). These should be designed with a
characteristic impedance of 50
or 75
and be properly termi-
nated at each end.
