  • THS3491: Some THS3491 2018 model noise testing,

    Resolved
    Part Number: THS3491 So I was kind of working on Steve Smith's sim vs. measurement question and thought I would step through some things, Here is the input current noise for the 2018 model - I had some analysis options set in V11 that was messing…

  • RE: THS3491: Noise modelling of THS3491 doesn't seem accurate

    Resolved
    Hello Steve, Wow, I cannot believe I did the classic "I will attach X" and forgot to do so. I believe Michael has reiterated it in his response, but I will append the TSC file here also: 7178.TINA Noise Sources revC (1).TSC Best, Alec

  • RE: THS3491: data on the GD2/HD3 validation

    Resolved
    Hi Mita, an OPAmp with a much higher supply current is a good candidate for lower distortion. A higher supply current allows the class AB output stage (and other internal stages) to be furtherly driven into the class A region. But keep in mind that an…

  • THS3491: How to interpret TJ_Sense.

    Resolved
    Part Number: THS3491 I'm looking for some guidance on how to interpret the TJ_SENSE specification for the THS3491. Since the test condition is to disable the part (Pd = 0V), the Ta is somewhat close to Tj, but what does the temperature value on parameter…

  • THS3491: How much can reduce the Rs when parallelling as a power source

    TI Thinks Resolved
    Part Number: THS3491 Hi Experts. Thank you for your support. and I'm getting very valuable informations on this site and your advices. This question is same project of my last thread. but unlike that thread, I also have to make voltage source (buffer…

  • RE: THS3491: Is it possible to use Cf to reduce the high freq. noise?

    Hi Winwoo, the THS3491 is a current feedback OPAmp and current feedback OPAmps don't like such low pass filtering caps in the feedback loops. Run a the THS3491DDA TINA-TI Reference Design (Rev. A) and look what happens when you add a Cf. Kai

  • THS3491: Unity gain setting

    TI Thinks Resolved
    Part Number: THS3491 Hello, I would like you to confirm whether THS3491 can accept unity gain setting or not. Because, according to datasheet, it seems that all spec is defined as 5V/V condition. Could you please tell me concern about unity gain setting…
