Can anybody explain me why we should split the digital ground from analog ground? Is it necessary to sperate the analog voltage from digital one? and every analog ic such as OPAMP should be considered as a analog part, for example a voltage follower?
I used an OPAMP to divided the voltage, I supplied the opamp's voltage by digital VCC and the GND of OPAMP was connected to digital's GND. Now, because I am not clear about the reason of grounding (I know the type of grounding like star ,etc.) so I am not sure that I should consider it as an analog part or not (becuase I think we should sperate the analog GND from ANLOG GND when the analog part is amplifying a signal, but here I am dividing the 3.3 voltage to 1.65 v by an opamp )?
Is it right or not?
