Hello,
On the datasheet there is no maximum for the VIH on the digital inputs.
On "7.4 Recommended Operating Conditions" the "Any input voltage" maximum is marked as (VA+0.1)
But remark 4 state "analog inputs" and not the digital inputs.
On the " EVM User's guide" linked on the part page the "Serial Interface" states "The range of all digital inputs is 0V to 5.25V regardless of VA"
If I use VA = 3V can I safely interface with 3.3V logic ?
Thanks
