I want to know which Tr/Tf is faster between AD8418 & AD8418A?
At Figure.11 , it look like AD8418A is faster.
But at Figure.15 & 17 , it look like AD8418 is faste.
Would you explain about this?
AD8418A is faster at small input signal, AD8418 is faster at large input signal?
And also I want to know which is better device for common-mode signal.
I saw the discussion attached below.
And also at datasheet , it look AD8418A is better.
But at application note look like AD8418 is better.
So, which is good to choice?
Can you give me an advise with explaining with how to chose AD8418 or AD8418A ?
