AD7124-SYNC pin  effects on ADC performance

Hello,

I have some questions regarding the SYNC pin. Periodically,I want to enable SYNC pin instead one time at start. Let us say, I have enabled 7 channels and set it to 70SPS. For firs set of samples(7 samples), it takes 100ms+settling time.  My question is that whenever I make sync pin high to start conversion, it takes settling time before doing conversion so that first set of sample will take time of 100ms+settling time(1/70sps) ?

 

And also I want to know that Periodically making SYNC pin high will affect ADC performance?

 

 

 

Thanks,

Muthu
