I want to driver AD9680 with DC couple.I find that it is very difficult to handle the common mode voltage between AD9680 and ADA4930 . With other ADC I can use the VCOM signal outputting from the adc as the common mode voltage to ADA4930. But there is no VCOM from AD9680. Anybody help.Anybody can provide some demo circuit of DC couple of AD9680 to me.Thanks lot.
