I have looked at many schematics. I have noticed that, some parts in the circuit are connected to GND, few are having AGND, some circuits(sensors) are having both the GND and AGND. Could some one please explain me what is GND and AGND and when do I need to separate them ? Also, If there is any application notes from popular semiconductors that would be a biggest help for me.
Thank you,
Ashok
