SMD Marking BGA Analog Devices

[testian]

I am struggling identifying the following SMD part:

Manufacturer: Analog Devices
SMD Marking:
  B
  GA
Case: MSOP8 (probably)

It should be an AD8671 but I am not sure, because the datasheet does not mention this code. Also searching for BGA in goggle is not very helpful. Does anyone have some resources where to look?

It looks like they removed that package from the datasheet.
