  • OPA859: FB pin of OPA859

    • Resolved
    Part Number: OPA859 Hello, I have two questions FB pin of OPA859 . 1) At "6 Pin Configuration

  • RE: WEBENCH® Tools/OPA859: PSPICE model for OPA859

    Hello Sima, Thank you for your reply. I could simulate of OPA859. Your answers and training videos were very helpful. Thank you very much, Ikuo

  • RE: WEBENCH® Tools/OPA859: Why is the Gain Bandwidth required in the Filter Design Tool Always so high?

    Hi Daniel, daniel_opa859.TSC On your other question later... Kai

  • OPA859: Input common mode capacitance

    • Resolved
    Part Number: OPA859 Hi, I am working on a differential probe with a the first opamp stages being

  • RE: PCB design - Inductance of PCB traces

    Hi Manos, What is the node 4 connection to the OPA859? To answer your question, vias only increase inductance if the signal is going through them, not along them. In your case, they will add the parasitic inductance of each trace in parallel, decreasing...

  • RE: OPA857EVM-978: OPA857EVM

    Hello Andrea, Kai's simulations should give you an idea of what to expect for transient simulations. I don't think the OPA857 is the correct device to use here as an integrator since the feedback is limited to either 20kohms or 5k-ohms. You...

  • RE: TINA/Spice/OPA859: Weird behaviour of output during power down

    Thank you Kai for your suggestion. There is indeed a reference to low output impedance associated with the protection diodes. I will consider it solved. Regards Manos

  • RE: OPA659: Question about current noise

    Hello George, Please use the 1.8fA/rtHz of the OPA659 as an initial flatband number of the current noise that will rise over frequency. Current noise at 10MHz will be closer to the magnitude of the OPA859 rather than 1.8fA/rthz. Best, Hasan Bab...

  • RE: LM7171: High gain bandwidth product OP Amp

    Incidentally, the OPA859 is one option -
