Connecting analog and digital ground planes
WebMay 6, 2024 · 10-12 bits or more. They will often discuss analog and digital ground planes. As I recall, the usual idea is to physically separate the analog and digital circuitry on the pcb, as you mentioned, and provide separate ground planes under each section, and then use a "single-point" connection between the 2 ground planes, WebMar 22, 2006 · The danger of connecting the digital and analog ground planes together is that the analog circuitry picks-up the noise from the digital return currents. In either case, the analog grounds, digital …

WebThat means that they dont overlap, at all. You don't put analog ground on the top and digital ground at the bottom. Everything to do with analog goes with the analog … WebJan 6, 2024 · Figure 4 is typical of circuits that have application notes or other guidelines that specify an analog ground plane and a digital ground plane or splitting the ground plane under the component. Doing either of these things detracts from the actual engineering problem of protecting the analog signal loop from external noise.
WebThe pin names analog ground and digital ground refer to internal connections in the IC, not the plane to which they should be connected. Both should connect to the analog ground plane. The connection would have been made inside the IC, but it is impossible to get low enough impedance at the typical geometries inside ICs. WebJul 9, 2024 · Question How should I connect the microcontroller pins in a system with a split ground plane? Answer If complete isolation between an 'Analog' and 'Digital' section of a board is required, the microcontroller should be placed entirely on one of the two ground planes.Which ground plane to place the microcontroller on depends on how it is being …
