• ADA4817-1　Power Down

    Hi,

    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

    Hi,

    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…

    Do you mean Ada4817-1? Yes, it is possible. Look at http://welecw2000a.sourceforge.net/docs/Hardware/Aktiver_Tastkopf_mit_OPA659.pdf

    ada4817 can replace opa659 there.

  • ADA4817 self-oscillation

    Hi,

    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…

    Basically you may build a simple oscillator with a high frequency & high slew-rate Op-AMP like a ADA4817-1

    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…
