and digital sections), and grounding. Digital
timing, calibration and the analog signal source
must be considered for correct operation.
To achieve specified accuracy, a double–sided
printed circuit board with a copper ground plane
on the component side is recommended. Keep
analog signal traces away from digital lines. It is
best to lay the PC board out such that there is an
analog section and a digital section with a single
point ground connection between the two through
an RF bead. If this is not possible, run analog
