opa192: Stability using DAC in feedback loop with OPA192

Part Number:opa192

HI All

I can send more details and full TINA file via email. Customer has a very interesting circuit using a DAC8811 in the feedback loop with an opa192. He is using it for a pga with gain -1 to -200. I am seeing some peaking at a gain of -1, can someone take a look at this circuit. Please email me directly.

Thanks
