THS4561: Use an THS4561 as Encode signal buffer.

Part Number: THS4561

Hi team,

I would like to know if the THS4561 can be used as an Encode buffer for DSP29379. 

Or do you have a better solution? thanks

    Hi Jimmy,

    For your application is it required to have a high impedance input to the buffer stage or by buffer did you mean an intermediate stage between the two? If this is required, there are other more complex options to do so. However, if you're simply looking for an attenuation stage with differential outputs your best option is to implement an FDA like you're suggesting in your diagram. Here is a good reference for how to implement an attenuation circuit with an FDA. 

    Best Regards,
