AD7837/AD7847 DAC interface

Question

Dear All, 
 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,

check your uC voh and Vol levels. 
 If Vih(max)>Voh>Vih(min) 
 and Vil(max)>Vol>0V 
 No problem.)

Hi, 
 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, please.
