I have build a system using AD9144 JESD DAC.

The version populated on my PCB is rev 0x02. (Read from register adress 0x06 field DEV_REVISION).

So far, I have been using datasheet rev 0, which also confirms that value.


I recently downloaded an updated datasheet which revision is now rev A

DEV_REVISION value is now 0x06 is this document.


I already noticed some difference in the recommended startup sequence: Required Device Configuration (table 85 or 88) are different.


So which datasheet shall I use?

Rev 0 or Rev A?
