most of analog design nowadays is getting the sign to the ADC, the ADC itself, and the clock generation for the ADC. The ADC is by far the most complex subsystem and it's partially digital partially analog, though the analog parts are also quite algorithmic (binary search, linear search, majority voting, LMS). The reverse path (DAC) is less common, like 10% of the cases you need a good DAC for signal generation. It's more hardcore analog and harder to design a DAC.
