AD5317R internal reference buffers

Question

It is a question about AD5317R.
When using the external reference, when using the internal reference, I think that the way internal buffers are different.
Please show us the arrangement of the buffer at this time.
I want a block diagram.

Best regards

Hi, 
 The reference section (including the ref buffer) is the same as shown in Figure 42 of the datasheet. 
 
 Cheers,

Hi Mochi, 
 Did you consider to use the AD5684? 
 12-bit resolution, similar core than the AD5317R but without internal reference, 
 Otherwise... why you don't use a FET.. it is pretty inexpensive,
