Hi,

this is somewhat a noob-question, but my skills in analogue hardware are 
limited.

The BeagleBones (and variants) come with six analogue inputs which each 
have a separate ground line GNDA and also a separate power supply VADC.

My questions here: how can I connect an external signal with 0..5V or 
0..10V to these inputs in order to read their analogue value?

And how about GNDA, has it to be separated from normal GND?

Thanks!

Mike
