    Hi guys,

    I could not found symbol of AD622 in ORCAD 16.3 and spice model file of this amplifier is also not available. Anyone please help me with alternate of the same.

  • PCN- Process Change Notice

    There is a PCN against AD620 and AD622 Instrument Amp. This is a major die revision change to the part. ADI claims there is no change to the spec. How do you confirm this claim if they do not publish the qual data for the new Die revision part?

  • RE: 用AD623搭建了一个电桥信号放大的模块,但是输出不稳定

    您好,我一共调试了两块电路板,两块原理图都是一模一样的,唯一的区别在于,一块用的是AD622,一块用的是AD623,之前说的AD623的电源电压是超过极限值的,但是AD622并没有超过极限值正负18V,而且之前说的输出不稳定的情况同样出现在AD622上,主要的表现有两个,第一个是偶尔会出现当天第一次上电的时候,他的输出值偏移的比较快,我用12位的ADC来采样,会在一个小时之内偏移20个左右的LSB,但是之后就比较稳定了,第二个就是正常情况下,在达到稳定的情况下,关闭电源,一段时间后再打开电源,大部分实验结果都会在半个小时之内慢慢偏移5个左右的LSB…

  • First output voltage of AD667

    Dear Sir/Madam,

     

    I have a question for you.

     

    As for your AD667 DAC,

    Before some setting to AD667, what voltage will be taken out?

    I think that 1st is max value(+10V in this case) ,and next it will move to the setting-voltage.

    Is this collect?

  • RE: Need Help using Eval inamp 62rz to amplify a Hall sensor output voltage.

    Hi Alex,

    Thanks for using ADI products in your application.

    The EVAL-INAMP-62RZ has its own user guide, the UG-261. For a quick start guide in using the evaluation board, kindly read page 4 to 6 of the user guide.

    Initially, the board is configured…

    I wanted to know whether the CMRR will be influenced by this different

    Take AD8221 for example.
    Case 1: supply the +5V single supply to it, the input signal will be Voff=2.5V,
    and the AC signal (under the frequency of 10Hz…
