Common-mode output voltage (V

μ
F filter capacitor should be connected between pin VCMA/VCMB and ground to
ensure a low-noise common-mode output voltage. When AC-coupled, pin VCMA/VCMB
can then be used to set the common-mode reference for the analog inputs, for instance
via a transformer middle point.
