A digital IC is an analogue circuit that has a signal in or a combination of signals in at a specific constant voltage but at varied times and that gives you a fixed voltage out. An analogue IC is an IC that uses the same components but it measures a varied voltage signal against another level that is not necessarily constant.
So if I have a pulse train in of a square wave then it acts as a digital signal. This is how data gets sent around.
If I have a voltage of 2 volts in that I want to compare to 2.4 volts then I would use an analogue IC or OP-amp.
Your analogue to DC converters take a voltage and changes it to a logic combination, say 1010111 for 3 Volts. You get dedicated IC's for this
