• OP297

    I have built a voltage amplify circuit with OP297GS.

    But sometimes, circuit does not work right, and that will not back to normal.

    There is an potentiometer before the Input pin (pin2), but I can't adjust output voltage.

    So, I exchange that OP297 with…

  • RE: OP97 / OP07 spice models

    The OP297 is the dual version of the OP97 so the OP297.cir model should work. I think the only difference might be that the dual version does not pinout the external compensation pin. If you are using that feature of the OP97 you might have difficulty…

  • RE: AD8639做电阻应变称重传感器放大器求助

    共模电压小于0.1V,现在用OP297和AD708工作正常,就是用AD8639不行。但用AD8639放大反馈信号,工作正常,放大电路形式与此电路完全相同,指示增益较低。反馈信号电压为±1.25V,放大后的输出为±2.1V。

  • OP279 output headroom

    what is the guaranteed output swing of OP297 with 120ohm load and +/-5V
    supplies? I need ~1.4V headroom.

     

    We will not provide guaranteed specs outside of those given in the datasheet. 
    The OP279 is generally spec'd for a 1k load. When…

  • RE: Tech support (SR#: 1201912)

    We are successfully using your OP amplifier OP297GSZ in our developments.
    However now we have to use the same one OP with MSOP-8 (or something like this)
    package. Please, could you recommend the replacement?

     

    Please have a look into the…
  • Noise optimizing AD8599 &&

    Good day,

    I have a task to optimize noise in BW 10Hz - 10kHz.

    Voltage gain shall be around 20..50. OA connected directly to source of signal,

    which has impedance 1kOm DC and 50Om AC. OA connected to middle point of R1/R2 divider,

    where R1 connected…

    Chapter 9 Hardware Design Techniques F.pdfHi XY,

    let me respond to your questions:

    If we use Buffer Mode, Output Additive Jitter is about 140fs. so total rms jitter for AFE ADC clocks should be roots.quare(100*100+140*140+54*54) = 180.3fs rms. Is my perception…
