what is the purpose of the analog part in the DAC


hi
why we can find DACs with simple analog circuit and some with very complex
what is exactly the purpose of the Analog part , as I understand it , the DAC chip output is analog 
does it act like a pre amp? even without volume control

thanks

abraxalito pontificated:
Not all DAC chips need an I/V stage, only those whose internal circuits work in current mode.
This statement is intellectually absurd. Many DAC chips incorporate the i/v stage inside the fab.
