    Hi,
    
 
     
    
 
    I am wondering if it is possible to use two AD5228 to perform as volume control for stereo signal? I am planning to use one up and one down button to achieve it.
    
 
     
    
 
    I am thinking to connect PU of two digipot together (same to PD), so that i can use one button each to control up/down for both AD5228.
    
 
     
    
 
    Is this workable? What is the logic output of PU and PD from AD5228?
