Digital and analog ground separation
WebI ask because the Analog Dialogue article states that the digital ground of an MCU must be connected to analog ground, for the sampling architecture to have the same reference as the analog elements of the circuit. However I have reason to believe the sampling architecture of the stm32f3 is connected to VSSA, and therefore can be separated. WebSep 22, 2024 · GND: Ground for the power supply; all analog and digital signals are referred to this pin voltage. ... Analog and digital separation with the ADS1274/1278. Make sure to connect AGND and DGND with a single plane! By routing away from the component in opposite directions, you’re putting plenty of space between the digital and analog …

WebMay 16, 2024 · Ground separation does not mean to "have a separate ground to the IC's power supply". ... Also, the separation should be maintained across whole PCB and to not cross sensitive analog section … WebJul 4, 2014 · Jul 4, 2014 at 7:36. 1. Connect all ground pins on the converter to the AGND pin of the raspberry PI. My point is that even if the ADC has separate AGND and DGND pins, they should both be routed to the analog ground. The converter DGND pin should not be connected to a separate ground plane.
WebIf you can keep HF noise away from the analog part you can couple both grounds directly, but at 1 point. When I worked with Philips Audio wired ferrite beads were sometimes used to connect digital and analog ground: DC resistance is in the milliohm range, but like Olin says they will offset ground for HF if you allow it to pass to the analog side. Webexample if the number of analog components is small compared to digital components, it may not be reasonable to dedicate an entire power and ground plane just for the analog components. Instead, a wide trace can be implemented on a signal plane to serve as the analog supply for the analog parts (See Figure 5).
