directly above the ground plane. Since the MAX5181/
MAX5184 have separate analog and digital ground
buses (AGND and DGND, respectively), the PC board
should also have separate analog and digital ground
sections with only one point connecting the two. Digital
signals should run above the digital ground plane, and
analog signals should run above the analog ground
plane.
Both devices have two power-supply inputs: analog
V
should be decoupled with parallel 10µF and 0.1µF
ceramic-chip capacitors. These capacitors should be
as close to the pin as possible, and their opposite ends
should be as close as possible to the ground plane.

to minimize analog load capacitance for proper opera-
tion. For best performance, bypass with low-ESR 0.1µF

The power-supply voltages should also be decoupled
with large tantalum or electrolytic capacitors at the
point they enter the PC board. Ferrite beads with addi-
tional decoupling capacitors forming a pi network can
also improve performance.
