Hi,
not really knowing what the output of Your DAC looks like any ´recommendation´ about a circuit is just blowing fog and fishing in muddy waters.
If Your DAC outputs a current it could well be more required than just a level shifting buffer.
We could help much better if we knew the current or voltage level and output impedance of the DAC, or even the parts name.
If the DAC puts out current a Current-to-Voltage converter is required, which can easily be made from a very simple discrete circuit, level-shifting included.

hi, thanks for your light , lot of fogs here..
the dac is a R2R discrete resistor ( french DAC called TOTALDAC )
(voltage out is 1V or so DC is 2.6V Z out is 10K)
i have order a quad of ZVN3310A to make a buffer. but to be honest i'm lost with the design of this buffer with my config
i begin to understand why many chose a simple Cap to get rid of the offset
