    Hi - hope you can help.
    
 
       Could you tell me AD7656 vs AD7656A-1 - are these devices pin-for-pin & Software compatible?
    
 
    If not, how do they differ?
    
 
    Many Thanks,
    
 
    Sam

    Hi Sam,
    
 
    Both devices are pin-for-pin and software compatible. The AD7656A-1 offers reduced decoupling requirements and improved power supply sequencing.
