Hello,

 

I have a question AD7768 one-shot conversion operation.
In this operation, DRDY has a delay(settling) time, which is required by filter delay, after /SYNC_IN.
I can see two kinds of delay time in table 36.
The one is
     "Delay from First MCLK Rise After /SYNC_IN Rise to First /DRDY Rise" --- (A)
and the other is
     "Delay from First MCLK Rise After /SYNC_IN Rise to Earlist Settled Data /DRDY Rise" --- (B)

 

Q1. When using by "one-shot mode", Should I refer to column (B) ?

 

Q2. What configuration generate the shorter delay such as (A) column ?

 

I want to make sure that the fisrt DRDY is genereted according to the column (B).

 

 

Best regards,

ysuzuki
