AD5304/AD5314/AD5324
POWER SUPPLY BYPASSING AND GROUNDING
In any circuit where accuracy is important, careful consider-
ation of the power supply and ground return layout helps to
ensure the rated performance. The printed circuit board on
which the AD5304/AD5314/AD5324 is mounted is designed
so that the analog and digital sections are separated and confined
to certain areas of the board. If the AD5304/AD5314/AD5324
are in a system where multiple devices require an AGND-to-
DGND connection, the connection is made at one point only.
The star ground point is established as close as possible to the
device. The AD5304/AD5314/AD5324 has ample supply bypass-
ing of 10 μF in parallel with 0.1 μF on the supply located as close
to the package as possible, ideally right up against the device.
The 10 μF capacitors are the tantalum bead type. The 0.1 μF capaci-
tor has low effective series resistance (ESR) and effective series

inductance (ESI), like the common ceramic types that provide
a low impedance path to ground at high frequencies, to handle
transient currents due to internal logic switching.
The power supply lines of the AD5304/AD5314/AD5324 use as
large a trace as possible to provide low impedance paths and reduce
the effects of glitches on the power supply line. Fast switching
signals such as clocks are shielded with digital ground to avoid
radiating noise to other parts of the board, and are never run
near the reference inputs. Avoid crossover of digital and analog
signals. Traces on opposite sides of the board run at right angles
to each other. This reduces the effects of feedthrough through
the board. A microstrip technique is by far the best, but is not
always possible with a double-sided board. In this technique,
the component side of the board is dedicated to a ground plane
while signal traces are placed on the solder side.
