Honored ContributorWhy Altera do not integrate ADC into CPLD?
Engineers welcome the integrated solution. It do help to save board size and save time on developing and debug work. As the CPLD performance is limited, so middle performance ADC is enough for C...

Honored ContributorBeside what has been mentioned, I doubt a fair number of significant bit is possible when the high currents inside a CPLD are switching. The ADC manufacturer hint that the ADCs need to be connected to the analog GND, which clearly is not the GND where the CPLD is on.
