• AD744电荷放大自激

    电荷放大如上图所示，实际测量中出现自激现象，RC滞后补偿和将R4变为1K已经尝试过，无法消除自激现象，自激波形近似三角波，峰峰值正负5V。这是什么原因，如何解决。为什么AD824不会出现自激现象

  • Creating Buffer front end circuit to read AD744 output signal

    Hi all,

    i don't have so much experience in circuit design and/or simulation.

    This is my situation:

    I have a PMT tube connected to a nuclear scintillation detector that makes available a test point that delivers semigaussian pulses.

    Before the…

  • RE: cancel JFET amplifier input capacitance changes

    Hi Francois,

    In addition, the major difference between ADA4817 and AD744 (the one used in the application note of Walt Jung) is that it uses different polarity of JFET (ADA4817: N-Channel and AD744:P-Channel). It means that the polarity of the Walt's…

  • RE: Recommend Opamp for integrator in audio oscillator

    Hi Mark,

    Yes I agree,selection of op amp is not easy. You should be able to identify which parameters your application should be of most interest.It could be the noise, precision or the cost for example.  If your going to choose between AD845 and AD744…

  • RE: Bottom view ? of AD549 fig47

    Hi Kaos,


    Shown on right side of Figure 47 of AD549 datasheet is the bottom view of the amplifier. Below is the outline dimensions for AD744 and you can take this as reference, it has the same package as AD549.



    Regards,

  • AD215 input offset adjustments

    Please teach me AD215.

    I would like to trim input offset.

    1.

    Do you have  a reference circuit?

    I think that it uses Trim Pin of AD744 in Fig23.

    But, in recent years, OPAMP with TrimPin is few.

    I checked AD203SN data sheet.

    Fig.20 and Fig21 are…

  • RE: Precision Opamp Selection for AAF (2nd order Sallen-key)- 24 channels 16 bit DAS

    Jebas,

    I can think of over 60 opamps with a 40V/usec slew and less than 0.5mV offset that run off 30V rails. I would also be looking for a low input bias current as a 200Hz filter needs large RC time constants, which you would probably want to generate…
