APPLICATIONS INFORMATION
LAYOUT
The printed circuit board (PCB) that houses the AD7944
should be designed so that the analog and digital sections
are separated and confined to certain areas of the board.
The pinout of the AD7944, 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 they
couple noise onto the die, unless a ground plane under the
AD7944 is used as a shield. Fast switching signals, such as
CNV or clocks, should not run near analog signal paths.
Avoid crossover of digital and analog signals.
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 AD7944 devices.
The AD7944 voltage reference inputs (REF) have 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 REFGND pins and connecting them with wide,
low impedance traces.
Finally, the power supplies, VDD and VIO of the AD7944,
should be decoupled with ceramic capacitors, typically 100 nF,
placed close to the AD7944 and connected using short, wide
traces to provide low impedance paths and to reduce the effect
of glitches on the power supply lines.
EVALUATING AD7944 PERFORMANCE
Other recommended layouts for the AD7944 are outlined
in the documentation for the AD7944 evaluation board
(EVAL-AD7944EBZ). The evaluation board package includes
a fully assembled and tested evaluation board, documentation,
and software for controlling the board from a PC via the
EVAL-CED1Z board.
