QCan I use split supplies of +3.3V for DVDD and +5V for AVDD on AD2S1200?
AThe AD2S1200 cannot operate on split supplies of +3.3V for DVDD and +5V for
AVDD. The supply voltage range on the datasheet for both AVDD and DVDD is
5V+/-5%. If you want to run the databus at 3.3V you will need to reduce the
AD2S1200 logic high output voltage from c.5V down to 3.3V max. However, 3.3V
signals flowing in the opposite direction, from the bus to the AD2S1200 don't
need any level shifting since the Vinh min is 2V.
