question about AD9218BSTZ-65 ADC

Hi everyone,

I used the AD9218BSTZ-65 ADC  and THS4130IDGN differential OP in my design.

The analog signal is 15Vp-p, and im dropping it to 1Vp-p using the differential OP.

The question is - is the ADC able to recive negative voltage in its Analog inputs? or must the voltage have a minimal DC level?

currently the Vocm is AGND, I suspect it needs to be 1V.

Im attaching my design. Thanks.

 

Regards,
