Ok well that isn't much help. I notice on the EVM schematic for the 4104 there is an option to use a separate 5V regulator for the references. That seems to imply that they need a fair bit of current, more than an reference ic could provide for instance.
So there is no other recommendations for these references?
It seems to me that these references would be fairly critical to the noise performance of the part and there would be more of a suggestion as to what they require.....
