is bigger than your noise specifiied. Does not make sense.
I'm guessing it is a reference bias with trim to manage for process and DES
* corners.
Integrated noise is going to be limited by how much filtering you can have, so I think the best approach would be the simplest: an 8 bit tapped resistor dividing down a reference voltage and feeding an RC low pass filter.
