AD8099 oscillation


I use AD8099 as the output buffer of the AD768, for getting a ±1.1V output voltage. Specific circuit is in the attachment.

When I test this circuit, I found AD8099 is oscillating. Is there any suggestion to eliminate the oscillation of AD8099?

In addition, I notice that, said in the datasheet of AD8099, compensation network values depend on the gain. In my circuit, how many I should regard the gain as?

Thank in advance for any help.
