(AD8206/AD8211)Why did you change the datasheet?

Hi !

I have some questions about ADI datasheet.

Our team are checking the datasheet because if the datasheet was changed we have to explain the changes.

And today , we found many datasheet was changed.

For just one example , AD8206 datasheet was changed.

I will attach the datasheet.

We found that P2 was changed

But the time stamp in the property was older than which I downloaded at past.

We always check the PDF property and the time stamp was older than the past datasheet so we are little bit confuse.

Also some parts changed the page number in spite of the datasheet Rev is not change.

Foe example AD8211.

When these thing happens , not only we are confuse.

Or customer will confuse too.

(We found same thing happens at these devices)

  AD2S1205
  AD605
  AD8205
  AD8206
  AD8207
  AD8210
  AD8211
  AD8417
  AD8418A
  AD9057
  ADA4571
  ADCMP361
  ADG719
  ADM202
  ADM3054
  ADM7154
  ADP1046
  ADR512
  ADuC7036
  ADuC7039
  ADuM3190
  ADXL312
  ADXL313

So my questions is ...

Q1)

Which timing would ADI change these kinds of pages?

Q2)

Also when you change these pages , why don't you change the revision?

We want to know this because we are checking and make the backup database for the datasheets regularly and it is very tough work when we found the updates.

Best regards.
