AD7722
the analog and digital systems. Fast switching signals like clocks
should be shielded with their associated ground to avoid radiating
noise to other sections of the board, and clock signals should
never be routed near the analog inputs.
Avoid running digital lines under the device as these will couple
noise onto the die. The analog ground plane should be allowed
to run under the AD7722 to shield it from noise coupling. The
power supply lines to the AD7722 should use as large a trace as
possible (preferably a plane) to provide a low impedance path
and reduce the effects of glitches on the power supply line.
Avoid crossover of digital and analog signals. Traces on opposite
sides of the board should run at right angles to each other. This
will reduce the effects of feedthrough through the board.
