Hello. I am designing a small pcb which contains a op-amp mosfet, a zener diode, micro-controller and a few passive components(no inductor).
The micro-controller is being used for ADC and the pcb is through hole design
My question is :
Should i keep keep on ground plane for both digital and analog?
OR
Should i be using split grounds and some how make them meet at the power return terminal?
1- I have never done a split ground plane--so might need guidance on that
2- I am using internal RC oscillator on the micro, so no external crystal
Thank you for the input!!
