Hi FVM and thanks for your reply. Can you please explain what do you mean by "good differential output amplifier design" ? In my project I have the differential outputs of the DAC driving an opamp and then the SMA output connector. I intend to place a lot of vias across the output lines and also isolate them from any digital circuitry on my PCB, in order to reduce noise. Is there anything else that has to be taken care of?
