The full-scale is programmable between 1 V (p-p) to 2 V (p-p) (see
Table 11.
An 0.1 μF filter capacitor should be connected between pin VCM and ground to ensure a
low-noise common-mode output voltage. When AC-coupled, these pins can be used to
set the common-mode reference for the analog inputs, for instance via a transformer
middle point.
