With regards input specification for Differential reference input

Hi , 

I am looking at LTC6948, the datasheet doesn't mention about REF+ REF- (1,28) input specification for differential input.

Could you please let me know the input specification for REF-, + when using Differential input .

Thanking you 

With best regards and wishes

    Hello,

    The LTC6948 (and LTC6946) differential reference input is very similar to the LTC6951 reference differential.  The only reason I mention this is we did a much better job in the LTC6951 datasheet showing preferred schematics for the differential case.  All of these circuits have been tested, just replace the LTC6951 in these diagrams with the LTC6948.  Hope this helps.
