APPLICATION HINTS
LAYOUT
The printed circuit board that houses the AD7982 should be
designed so that the analog and digital sections are separated
and confined to certain areas of the board. The pinout of the
AD7982, with its analog signals on the left side and its digital
signals on the right side, eases this task.
Avoid running digital lines under the device because these
couple noise onto the die, unless a ground plane under the
AD7982 is used as a shield. Fast switching signals, such as CNV
or clocks, should not run near analog signal paths. Crossover of
digital and analog signals should be avoided.
At least one ground plane should be used. It can be common or
split between the digital and analog sections. In the latter case,
the planes should be joined underneath the AD7982s.
The AD7982 voltage reference input REF has a dynamic input
impedance and should be decoupled with minimal parasitic
inductances. This is done by placing the reference decoupling
ceramic capacitor close to, ideally right up against, the REF and
GND pins and connecting them with wide, low impedance traces.
Finally, the power supplies VDD and VIO of the AD7982
should be decoupled with ceramic capacitors, typically 100 nF,
placed close to the AD7982 and connected using short, wide
traces to provide low impedance paths and to reduce the effect
of glitches on the power supply lines.
An example of layout following these rules is shown in
EVALUATING AD7982 PERFORMANCE
Other recommended layouts for the AD7982 are outlined
in the documentation of the evaluation board for the AD7982
(EVAL-AD7982SDZ). The evaluation board package includes
a fully assembled and tested evaluation board, documentation,
and software for controlling the board from a PC via the
