Connecting AD8370 VGA to AD9246 A2D in DC coupled mode


I'm trying to find how to conenct the AD8370 Variable Gain Amp to the AD9246 A2D working at 2Vptp mode.

The connection should be DC coupled. THey got diffewrent common mode voltage levels so this problem should be solved.

I contacted technical support and they suggested using AD4938-1 amplifier between them. I already use this amp with teh same ADC but I don't know how to connect the AD8370 to that amplifier. I attach a drawing of my current circuit which already got an AD4938 connected to AD9246.

Anyone can help?
