I'm designing a board with the DAC DAC5681. Reading the user guide in which there's the electrical drawing of the EVB, I need the balun transformer at the DAC output to have a single-ended 50 OHm net. This is also the default configuration in your EVB, because you use the output connector J1 (IOUTB2), see the attached file.
Could you tell me what output coupling has the DAC output using the balun transformer with the default configuration?
I look forward to hearing from you.
