In case that VDDO_0 (pin 83), VDDO_1 (pin 93), VSSO_0 (pin 81) and VSSO_1 (pin 95) is unused, what termination is required?
The supply pins you mentioned above are still connected internally to the supplies of the ADATE305. They should still be shorted to VDD and VSS respectively. The reason for their special mention on the datasheet was so the user can pay special attention to them during supply decoupling. In case the driver is not being used, These pins should still be powered up while the driver is placed in a Hi-Z mode via SPI command.
Understood.Thanks for clear answer.
