QCan the AD9684 support DC coupled signals?
AThe AD9684 can support DC coupling if the common mode voltage is kept at the
recommended level. In DC-coupled applications, set the common-mode voltage to
2.05 V, ±100 mV to ensure proper ADC operation. The full-scale voltage setting
must be at a 1.7 V p-p differential if running in a DC-coupled application.
