AD7934 full-differential mode

Dear All,


I'm using AD7934 with FPGA interface. I want to use AD7934 in differential mode.

I've used AD8138 for converting single-end to differential signal.

ADC is working in single-end mode (M0=0,M1=0) quite nicely. I tried all four input channels VIN0-3 in single mode all are working nice.


But When I configure ADC  for fully diferential and even pseudo differential mode but no success. Output keeps fluctuating.


Kindly help me


Thanx in advance
