DAC3484EVM: DC coupled single ended output

    Please advise on the circuit between DAC3484 and a differential to single ended op-amp THS3217. 



  • Hi SM,

    Did you mean to attach a schematic?

    If not, for the circuit between the DAC3484 and THS3217 there are a couple of things that you are going to have to take into consideration.

    • You will have to make sure that you are terminating the DAC outputs correctly. You will need to choose the proper termination such that the DAC output voltage does not exceed the compliance range of the DAC.
    • Make sure that you are DC coupling the outputs correctly.
    • A filter may need to be inserted between the DAC and Amp in order to reduce the amount of noise the Op-Amp will amplify.
