The AVDD and DVDD of the AD7864 are connected to a 5 V power supply and VDRIVE is connected to a 3.3 V power supply.
In this case, what is the value of VOL and VOH of the output drivers (DB0 to DB11), BUSY, EOC, FRSTDATA?
The datasheet is missing some information for this case.
You may use a value of 0.8V for VOL and 2V for VOH for a 3V Vdrive.
