I'm using LTC2642 in unipolar configuration and datasheet suggest connecting RFB and INV pins to VREF. But as it's hard to do it in my layout I'd like to leave them unconnected. I don't think that would cause any problems as those pins seem to be internally connected only to resistors. The DC1096B schematic also shows those pins unconnected for DAC1.
Does anyone think leaving RFB and INV pins unconnected in unipolar configuration could cause any problems.
