I am trying to figure out how it works. here are what I have understood..
- the counter sequence is 1000 1100 1110 1111(assuming 4 bit conversion).
-1st the output of counter is 1000 this is converted to its analog(by D/A) and
compared to the input by the comparator. where is the output of the comparator connected to the SAR?
-The inputs to the DAC are connected to SRG ,what is that?
How does the circuit know when the conversion is done??
Hope you understood my queston!!
