Hi guys! i have a question about ADC . when we say that ADC has completed its conversion what does it means? Either its is the maximum value of ADC registers or complete cycle has digitized.? please help me to understand this concept. thankx

How does an analog-to-digital converter work?
It receives an analog voltage and it has to do some legwork in order to convert it into a number. What it actually does depends on the design of the ADC. There are a number of methods for doing this. Some methods are fast while others are slow. All methods take a duration to complete. When the ADC has the answer it notifies the rest of the computer system that it is finished by sending a "conversion completed" signal.

This duration is called the "conversion time" and would be specified in the ADC specifications data-sheet.
