ADR444 reference design for noise reduction?

Question

We need reference voltage of 4,096 V with the lowest noise. 
 We try ADR444 + output filter + pA low noise buffer amplifier. 
 Before we start counting and beating a dead path, you do not have a appnote or reference design with similar problem? 
 For specify. We need voltage reference with 0.1-10Hz output noise ~250nVp-p 
 Capacity how much can hang on output ADR4xx?

Zuzuna, 
 I would use the ADR434. It's my favorite reference because it brings out an internal node, COMP, 
 allowing you to over compensate the loop and avoid noise peaking. See the "high frequency noise" 
 write up in the apps section of the data sheet.
