OPAx316 as Buffer for ADC Common Mode biasing

Hi team,

I'm looking for a way to drive the Common Mode for an ADC.  We're looking to drive 875mV @ 4mA to set the common mode on the ADC input pins.  The device should also be able to drive a cap load of 0.8uF, which is fairly large.

I was looking at the OPAx316 for this, but due to the size of the capacitive load I believe I must compensate the circuit.  I would be using the Op Amp in a buffer configuration from a resistive divider input.  I think perhaps I'll need dual feedback and an isolation resistor.  Could you help me with the circuit design for this application?  

Thanks,

Kareem
