The AD5664R has two on-chip reference options available, 1.25V and 2.5V. What is the recommended supply voltage in each case?

      Hi Pradaic,
      
 
      In AD56x4R datasheet (Rev C.), it is said (External Reference chapter, p20) that "All devices (AD56x4R-3 and the AD56x4R-5) can be operated from a single 2.7 V to 5.5 V supply."
      
 
      Above you are stating that "The 1.25V internal reference option will work between a supply of 2.7V to 3.6V".
      
 
      Which is right?
      
 
      Could AD56x4R-3 uses +5V supply?
      
 
      My design uses AD5664R-3 and I connected its supply to +5V.
      
 
      Regards,
