What is the difference between different types of GND I would like to know the difference between different types of Grounds like AGND, SGND, Battery Gnd, PGND Are all the grounds not same? Cant we connect the device to any one of these grounds?
AGND and GND - Electrical Engineering Stack Exchange AGND and GND are generally "Analog Ground" and "Everything Else Ground" The general reason they are separated is that AGND is the reference to sensitive analog circuits (amplifiers, ADCs, DACs, etc ) and GND is the reference for general digital circuits (gates, shift registers, MCUs, CPUs, FPGAs, etc ), which can impart a lot of switching noise onto their grounds Now, you want your
Can I connect two power supplies GNDs together? Can should I connect the two power supply GND togheter? Yes, generally you must unless there is a good reason not to do so But then you would know that In general circuits need to share the same ground in order to work Also if you don't connect the grounds together, there is the risk of damaging one or both boards
Ground vs. Earth vs. common vs. negative terminal Assuming these statements are true then why is the term "ground" (primarily) or sometimes the symbol for "earth" used so extensively in electrical circuit diagrams? Why is it ground or earth, rather than just a negative terminal, or a 0V terminal, or maybe just a "common" terminal? The use of ground or the earth symbol, particularly in IC circuit diagrams (which are not necessarily used in
grounding - What is the best practice to connect isolated CANBUS . . . Its GND reference is not the same as the other devices (with the same DC2DC), i e both have floating GND Questions: How does isolated DC2DC behave? What prevents the GND of device B and device A from being slightly different in magnitude? What is the most suitable way to connect the GND to ensure that the reference is the same?
Connection between Chassis GND and Circuit GND for ESD transients The circuit GND is connected through a TVS to chassis GND for 14-14, but in the other two, the circuit GND is connected directly to chassis GND Is anyone able to reconcile this? How do I reconcile that? Easy! The author just meant to show the situation in which the TVS shorts due to a transient event
schematics - Use of ground symbols in circuit diagrams - Electrical . . . The bottom of R2 should connect directly to the GND pin on the TPS61200 to avoid power-ground noise upsetting the feedback and regulation of this device (and most other switching regulators should they have separate pins) So, is this question just about the interpretation of symbols?
How to interpret Vcc and GND on integrated circuits? It is necessary to consider how to power an IC (via Vcc and GND pins) However, it is not sufficient to ensure an entire circuit will work As well as power and ground, the vast majority of (Vcc GND powered) ICs also have input and output signals These signals must be considered too as part of a practical solution
ISO IEC Power Ground Symbol in schematics? Some argue that using the horizontal 4-lines symbol for GND is a misunderstanding because this is not a real ground Others say that only arrows are valid On the 60617-2 snippet below, one can see that in French, the 02-15-01 symbol is named "Terre" (Earth) in french, but "Earth Ground" in english
