Can i make interface with DAC ( AD7837) using Microprocessor have I/O ports with logic voltage levels equal to 3.3 volt??
and if not there is DAC with logic level I/O equal to 3.3 volt??
Thanks in Advances,
The AD7837 has a Vih = 2.4V/VIl = 0.8V, this means that your digital signals can be as low as 2.4V for a logic high and a maximum of 0.8V for a logic low.
Let me know if you have any other question…
but in this table, 2.4 have Vmin unit and 0.8 have Vmax unit, that means that logic high is from Vdd=5v to 2.4v and logic zero from 0v to 0.8v??? I understood that from this table !.
if i interface this IC with 3.3 processors, there is no problem??
