Hi,
i was wondering whether I can interface a DAC70501 using I2C when the I2C bus is at 3.3V (and pulled-up to 3.3V) while VDD of the DAC70501 is at 5V.
Obviously I want to save having to use level converters and according to the datasheet, everything from 1.62 is considered HIGH so I should be safe from this point of view.
However at the pin description text, the description of SDIN/SDA says that it has to be tied to supply voltage, which would be contraindicative in this case.
I guess the statement regarding having to pull the pin high has been made because this is how I2C works but I want to make sure this will work before I make the first test batch of PCBs.
VDD is going to be 5V so I can go up to that voltage on the DAC output, obviously. Only having 3.3V at the output wouldn't fit my needs.
Thanks!
