    FAQ

  • OP37

    I will start this with a basic overview of our problem.

    We designed a baseband amplification board to amplify a baseband signal through two OP37 SOIC-8 stages. The original design specs were that we would only be dealing with positive voltage inputs…

  • radiation effect on OP37

  • OP37: Reversal of supply voltage

    Q 

    I have had a query from a customer they have wired an OP37 incorrectly.
    Instead of +15V and 0V they have applied -6V on the V+ pin and +5V on the V-
    pin, the parts were then powered up and the error realized.  The problem was
    corrected and the…

  • phase shifter using OP37

    hi

    i am trying to develop a phase shifter using integrator concept. working Range 10KHz to 1MHz.

    considering High frequency i am using OP37 which has high Gain bandwidth and slew rate.

    i am Facing a problem with instability in output signal.

    Problem…

  • ADA4637-1 and OP37 pin compatibility in SOIC

    Q 

    Are ADA4637-1 and OP37GSZ in SOIC package pin compatible?

     

    A 

    ADA4637-1 and OP37GSZ, are not pin compatible. But if you can externally short
    pin 5 and 8, then they become pin compatible.

  • SPICE Model on website VS Model in LTspice XVII - OP37

    I was experimenting with the simulation model of the OP37 available on the website. Then I realized that there's also a model available in the LTspice XVII as well. But the models seem to have different frequency responses.

    So my question is which…

  • RE: OP27和OP37搭建的放大電路振盪

    op37的电源抑制比还是蛮高的，50k时有40db，如果op37的电源上有20mV的噪声，道理上来讲输出噪声会被衰减到1mV以下的。
    不过您可以尝试一下，直接用较好的源给op37供电，看是否还有同样问题。

    请问OP37S和AD574S这两个宇航级型号的结温（Junction Temperature）最大范围是多少？

  • 我用OP37,OP27,AD8021等一些速度较快的运放接成跟随器时输出噪音大

    我用OP37,OP27,AD8021等一些速度较快的运放接成电压跟随器,用示波器观察输出(输入端短路),结果噪音很大,峰峰值有十几毫伏
