• ADA4817-1 Power Down


    My customers are considering ADA 4817-1.

    So I got a question.
    It is about operation in the Power Down state.

    #1  Is the input pin High-Z (high impedance)?

    #2  Does the current leak from the input pin?

    Best regards

    Hi Premsagar,

    ADA4817 would work but it requires a minimum Vs=5V. The closest fit for your application is LTC6268. Let me know if this works. Also, could you share what your application is?



  • ADA4817-1 Input impedance change


    My customers are considering using ADA 4817-1.

    So I got a question.

    Does the input impedance vary with frequency?

    If it changes, how will it change?

    Best regards,


  • ADA4817-1 differential to single end

    I use ADA4817-1 to convert differential voltage to single end. The common voltage is +0.3V ~ +0.7V, and the differential voltage is about 5mV to 2000mV. The source impedance is about 5k ~10k Ohm. Signal frequency from DC to100MHz.

    The simple circuit…

  • ADA4817 self-oscillation


    I use ada4817-1 and adg1414bcpz to convert current to voltage.

    But the amplifier self-oscillate at frequency about 80MHz.

    How can i cancel the unexpected frequency?

    In attchment, ADA4817-1 convert current in DUT to voltage. ADG1414BCPZ used to…

    Dear Gauzz

    TanQ for ur reply

    before your answer, I did some simulations by spice models of two AD8067 in series and a composite of a AD8067 and a AD8009 and found improvements by composite configuration against two series amps.

    now I have an another question…
