you need to use the digital ground for the digital components in the circuit and the analog for the analog circuits. this help to reduce the switching disturbance coupling from digital circuits to the analog

What worries me is that you are asking such a basic question on electronics yet laying out PCB's, you need to learn some basic electronics first me thinks!
If you are using Analog to Digital converter or digital analog converter you will come to know easily. It will be mention in data sheet. both the symbol representation will be different. just Google it for symbol.it depend on your purpose.
Hi vivek,
depends on application the component select is vary.for digital circuit you have to choose component less than or equal to 5v.for analog circuit depends on voltage it will vary

Those components which handles analog signals need analog ground as referance. those handle digital signal need digital ground. for an ADC usually have both.
seperate both grounds with a bead (or 0 ohm resistor!)
