The article would improve a lot when adding how the analog circuit design ensures to have low noise on the measured signals and power supply. The schematic shows CRC Pi filters and ferrite beads, but you don't mention them here. Please describe how to achieve stable supply and low-noise signals, using proper circuit design and layout rules.

Good question, though not particular to this application note. Indeed, it pertains to most circuits one might build. There are whole books on the topic.
I talked to tech support for some additional guidance and they suggested application notes 899 (http://www.maxim-ic.com/an899) and 3657 (http://www.maxim-ic.com/an3657) may provide examples of noise reduction. There is also the very popular DC-DC Tutorial (http://www.maxim-ic.com/an2031) and our power supply cookbook (http://www.maxim-ic.com/cookbook/powersupply/) gives many tested circuits. Finally, many of the data sheets for power supply products include components and discussion of ways to keep a power supply relatively noise free.
There is also an app note on low-noise pc board design considerations: http://www.maxim-ic.com/an4079
