Today\u2019s Everyday App Note is flying in from <\/span>Analog Devices<\/span><\/a>, a leader in the design and manufacturing of analog, mixed-signal, and DSP integrated circuits. It\u2019s time to put away your high-flying theory; this app note is all about getting grounded. In an ideal world, there would be one grounding method to rule them all, but this isn\u2019t reality. In this app note, you\u2019ll learn the best-of strategies for grounding mixed-signal applications.<\/span><\/p>\n\n\n\n

Who Is This App Note For?<\/h2>\n\n\n

This app note was made specifically for digital or analog designers working on mixed-signal devices. Both specialists have their own unique perspective on a mixed-signal application, so this app note keeps grounding techniques general to apply to both worlds.<\/span><\/p>\n\n\n

Why Should You Read This App Note?<\/h2>\n\n\n

Grounding might be a simple concept, but its actual implementation is incredibly complex and challenging to master. In linear systems, ground serves as both a return path for a power supply current and a reference for signals. Using the wrong grounding strategy to satisfy these two requirements can destroy system performance.<\/span><\/p>\n\n\n\n

For mixed-signal devices with analog and digital connections, choosing the right grounding strategy becomes even more of a challenge. Whether you\u2019re working with low digital currents or high digital currents, both will require their own preferred grounding approach. This app note covers enough techniques to satisfy both design requirements.<\/span><\/p>\n\n\n

What Problems Does This App Note Solve?<\/h2>\n\n\n

The ugly truth is no universal grounding method guarantees100% performance for any design. Instead of going with a one-size-fits-all approach, this app note covers a variety of grounding strategies that will allow you to take control of problems like:<\/span><\/p>\n\n\n\n
