I'm looking at a DAC that uses the DF1704 and I'm having trouble finding pin 1. I know the large recessed dot should mark pin 1, but if this is the case on this design, then the pin opposite pin 1 (pin 28) should be LRCIN and this seems to not be connected to anything. I'm not sure how this would be possible, as none of the applications in the manual for this chip show it being operated in this fashion. The only thing I can guess is that pin 1 is somewhere else... sorry for the basic question, but I'm not really sure what's going on here. Package is SSOP-28 and it is marked Burr-Brown (not TI).
