• Question about the close-loop AC-Sweep simulation result of ADA4625-1

    Hi,

    I'm using LTspice XVII (newest version), the simulation model of ADA4625-1 I downloaded from AD's official site.

    I'm going to design an inverting voltage amplify circuit with a gain of -10.

    The simulation circuits are as below:

    What is the MTBF and FIT value of ADA4625-1ARDZ?

  • ADA4625-1 LTspice Model Offset Voltage

    Hello,

    when simulating ADA4625-1 configured as simple unity gain buffer in LTspice with single 5V supply (Vs- =0, Vs+=5V), I get a systematic DC offset of -45.406mV which is far beyond the max value in the datasheet (+/- 1mV max). Is there a problem with…

  • ADA4625-1 Crossover Distortion

    Hi,

    I am using the ADA4625-1 in a Digital to Analog Converter analog stage. I sometimes to like to use a current source to bias op amps into class a to reduce or eliminate crossover distortion. However, I noticed in the ada4625 datasheet that it says…

  • ADA4625-1ARDZ Noise LEVEL

    Hello
    I am using ada4625-1 of analog device.
    It is used as a Transimpedance amplifier and uses a total of four.Let's call this one channel each. Rf is 5.1MEG and Cf is 3pF.
    However, only one channel has a high noise level. We suspect that the device…

  • LTspice - ADA4625 simulation unsuccesful

    Good day.

    I need your help. I downloaded your LTspice software and tried to simulate circuit with Opamp ADA4625. Simulation was unsuccesful. When I changed the opamp for ADA4622, it worked great. Is it a problem with ADA4625 Spice model? Could you check…

  • ADA4625-1 application without the -VS

    hi

    i have used the wizards help to create a design using the ADA4625-1

    my question is - do not have an option for -VS on my board

    if i ground this pin would i get only half the amplification?

    how else would this effect my design?

    thanks

  • ADA4625: what does IVR parameter means?

    Hi, 

    I'm not sure what does the IVR parameter of the ADA4625-1 part means. 

    Is this the same as input common mode range parameter often used in datasheets? If so, and the Vcm = 1.5 as stated above the table, does it mean that the all the table is…

  • ADA4625构建放大器有直流量输出

    各位工程师大家好,

    我用ADA4625构建了一个同相比例放大器,如下图所示:

    在使用时遇到了一个问题没搞清楚,想向大家请教一下,
    对于这个放大电路,当我用信号发生器给一个正弦波输入进去时,该放大器可以正常工作,实现放大倍数可调的效果,
    但是当没有信号输入时,这个模块输出一个直流电压,请问这是什么导致的啊,正常吗?
    是因为我正负输入端的阻抗不匹配造成的吗?
    我自己不是电子专业出身,最近刚开始接触,
    可能问题比较基础,但是对我来说确实没搞懂,
    望大家解答,感谢!
  • RE: what is the current noise density vs frequency for the ADA4625

    Is there any update on this topic. I too am looking for info on the current noise at low frequency. I intend to use ADA4625-1 for a unity gain buffer following a passive R-C filter ~1 MOhm + 20 uF (CDE #935C1W20K-F) and would like to estimate the noise…
