PCB Design Guidelines for Analog Circuits
This strategy helps in absorbing the noise by the analog GND plane and avoids interference with the digital circuit. It's highly recommended to place and route analog and digital circuits separately and avoid any high-speed digital routing in the analog section.
What are PCB standards?
For PCB designers, the must-read IPC standard is the IPC-2221. The IPC-2221 is the generic standard that covers almost every aspect of PCB design. The standard details how electrical considerations such as PDN bus layouts, conductor clearance, and impedance control should be implemented on a PCB.
What is the best way to isolate digital and analog circuits on a PCB?
The recommendation is usually to split the PCB ground plane into an analog plane and a digital plane, with the further recommendation that the AGND and DGND pins of a converter be tied together and that the analog ground plane and digital ground planes be connected at that same point, as shown in Figure 8.
