    Hello!
    
 
    I have a Problem with the AD5627R. (in MSOP Package)
    
 
    The Output is not Rising higher than 0,3V (@ 0x0FFF),  When I change the Input the Output follows so I can see it works somehow.
    
 
    I am using the internal reference ( I have 2,42V on the reference pin) but I  also tried to switch it off and use an external 2,5V reference. In this Case my maximal Output is 0,15V
    
 
    I also tried to change the supply Voltage   from 3V3 to 5V, but nothing changes.
    
 
    I Pulled the LDAC to Low and CLR to High,
    
 
    For Initialisation I set the Internal Reference :On and the Power Down Mode: Normal Mode.
    
 
    I write every 50ms one Channel
    
 
    Also I Can see on my Logic Analyzer that the Conversation is good. 
    
 
    Anyone a Idea, it will be very helpfull. 
    
 
    Thanks..
    
 
    Martin
