What is the maximum capacitance I can put on the VCM pin. I am using VCM to bias my ac coupled inputs and I am getting some crosstalk and noise coupling between channels - I believe via VCM. Currently I see about 15mV of noise on VCM. I would expect a significant amount of the noise should be eliminated as it will be common mode but it seems like there is still some effect on the signal.
