I develop an application where I use a AD7988-5 with an interface to the processor with 5V signals.
VIO=5V (For the 5V interface)
But now I measure:
that the SDO high level is only at 2.5V.
In the Datasheet is written:
VIO − 0.3 V
So the SDO level should be between 0.4V and 4.7V or do I understand something wrong?
Thanks for any help
