Hello,

I'm currently designing my first Pcb and I don't know how to stack-up the layers. I
The following list shows the components i'm using in my design:

Arduino : +5v
Ad9833 module: +5V
Amplifier : ±Vcc or ±5V
Multiplier (Ad633) : ±Vcc (Vcc > 8V)
Switched Capacitor Filter (Max293) : ±5V
Clock / Silicon Oscillator (LTC6900): +5V
Dc-Dc converters: +5V ---> ±Vcc & -5V

Can I use a single layer to create ±Vcc and ±5v power planes?
The Ad9833 ic has one analog ground pin and one digital ground pin. The Ad9833 module has one ground pin. Should i connect the module's pin and the arduino ground pin to a digital ground?

Sorry for my English
Thank you.

What the difference between a signal plane and a signal polygon?

As for you question, yes, you can put large signal (say power or ground) polygons on the same layer. Why? Maybe there is a good reason -- like a one-sided board or power needs.

When you do that, you will probably want to assign a rank of 1 to one signal (e.g., ground) and a lower priority rank to the other polygon. In my system, the higher the rank, the lower the priority.
