VCOM centered ADIN for AC coupling
The Test register (D6) is for the AC coupled ADIN
input mode. At this mode, the DC bias becomes the
VCOM voltage and no clamp signals are required.
Connect a 50 k$ resistor between the ADIN (pin
14) and CLPCAP (pin 13), and input the signal to
the ADIN pin via a capacitor.
