My architecture is base on ADC+FPGA+DAC.Left terminal DAC signal is amplified by OPA2673. It passed twist_pair and transformer and loss it power.
I supposed it won't broke right adc.But in lef terminal,adc is not isolated to opa2673. I supposed it would broke my left adc.
If my suppose is right.how to fix this problem.
Is there some reference design about opa2673 used as xdsl driver?
Thanks for your favor.
