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
