I'm pretty sure, but...
Is it possible to shut down halfs of ADL5566 idependently to each other, pulling down the corresponding ENBL?
Is it nessesary to supply a power to unused VCC? And what about rest pins? Inputs, outputs and VCOM?
Actually, the adl5566 has ESD diodes across Vcc so you will need to maintain voltage on the unused channel and put the part in disable. (this will burn an extra 8 ma).
Also, it would be best…
