Hi,
I've been asked to compare the delta sigma ADC and DAC circuits as part of a college assignement. I've done the ADC section as I'm happy that I understand what's going on, but I can't get my head around the DAC version.
Can anyone give me a quick walkthrough of what's happening at each stage?
I've attached the flowchart diagram that I have but I don't understand what the MSBIT does or why the circuit feeds back to the adder from the latch output.



Thanks
Dave
