AD9257 ADC driver and VCM output buffer recommendations

Hello,

 

I am using the AD4932-1 to drive the ADC inputs for an AD9253 in a current design.  Is this still the recommended driver amp for my application?  If so, I currently use the VCM output of the AD9253 to drive four (4) AD4932-1 opamps.  If I move to the OCTAL can I drive eight (8) opamps with the AD9257 VCM output or should I buffer?

 

Thanks.
