• 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…
