    Hello,
    
 
       I required an high speed ADC with bipolar analog input ranging from -V to +V. I was considering AD9042 but later on it came to my notice that it does not take in bipolar analog input. So, right now I am considering the following ADC's for the same purpose:
    
 
    1. AD9246
    
 
    2. AD9254
    
 
    3. AD6645
    
 
          I do not have any information yet regarding whether these devices take in bipolar analog input or not. I request you to inform me whether any of these devices fulfills my requirement.
    
 
    Thanks
    
 
    Regards

        Hello Doug!
        
 
        Thanks for your reply. Correct me if I am wrong. As far as I understand, differential input means that difference of two incoming signal will be taken as input. However, that does not necessarily mean that it will take in positive and negative analog signals as input. I need an ADC which can have say -5V to +5V input range with around 50MHz analog input bandwidth.
        
 
        I am not sure if differential and bipolar are the same thing. Please help me fill in this gap in my knowledge.
        
 
        Also please do suggest me any high speed bipolar ADC if present.
        
 
        Thanks
