The output voltage from [AD5611][1] DAC is rail-to-rail, and minimum Vcc is 2.7V - therefore, the signal range is 0-2.7V. I need to attenuate this signal to let's say 0-2V range. The DAC output is very weak, so I need to use an OpAmp to buffer it. Is it a good practice to use **G=<1** configuration for decreasing signal's amplitude, or is there a better way to do it?

I saw [this][2] question, but I do not think that using voltage divider would be a good idea in my case, since the DAC output is very weak, and using large resistances would introduce noise.
