• ADG1409: ADG1409: Process technology / MTBF

    Would you pls help check the process of ADG1409? In the reliability page, I
    can not find this part? 

     

    The ADG1409 is built on 0.6u High Voltage CMOS
  • Re: Mux ADG1409

    Hi Joaquim,

     

    There is no spice model available for the ADG1409.  The spice models we have available are at this site http://www.analog.com/en/tools-software-simulation-models/resources/index.html

     

    Please send a copy of your schematic for review.

  • ADG1409 for switching power supply

    Hi all,

    I want to switch two power supply (+5V and +12V) with an ADG1409 mux to 4 differents outputs. Please see attached image.

    I use U15 to select the power supply. With A0_1 == A1_1 == 0 in DA pin I will have +5V, and with  A0_1 == 0 nad A1_1 == 1…

  • ADG1409 for switching power supply. Drop voltage

    Hi all,

    I have a problem with this circuit. I'm using this circuit to mux two power supplies (+5V or +12V) to 4 different outputs (+EXC1, ..., 4).

    To generate +12V I'm using a Step Up. This step up generate +12V @ 30mA and it is limited to a 40mA…

  • Parameters I can change Spice models - ADG408/ADG409 to match behavior - ADG1408/ADG1409?

    Are there some parameters I can change in the models for the ADG408/ADG409 parts to match how an ADG1408/ADG1409 would operate?

    I have both spice models downloaded: AGD408/ADG409

    I would like to simulate ADG1408/ADG1409

    Thanks.

  • RE: I-V  通过249R电阻转电压1-5V 的问题(附图)?

    我的问题不在AD8226芯片上,在AD8226端做转换,没有问题呀!而问题出在ADG1409四路通道切换开关上。在ADG1409的输入端,测试4.98V(测试点B),而在ADG1409的输出端,测试电压仅有1.56V。其中有3.42V却消耗在ADG1409上。。。。我的问题是,如何在ADG1409的输入做一些电路变换,可以在输出得到4.98V左右的电压。


    这个问题希望能尽快得到回答?


  • RE: Single AD598 with 8 LVDTs with Multiplexers

    Hi,

    Apologies for the delayed response here,

    I think you are on the correct track here with the ADG1409. the first thing to think about when selecting a switch is the Supply voltage and the voltage you wish to pass.

    If you are using a +/-15 V supply…

  • RE: I-V  通过249R电阻转电压1-5V 的问题?

    建议先断开AD8226和ADG1409,单独测试开关的功能是否正常。

    另外,也可以将您的原理图粘贴上来查看一下。

  • RE: ADG1408

    Thank you for your answer, I have already found the error, it was in the microcontroller's code. ADG1409 is really much more suitable for this application, but it is only a prototype, in final version of the device all chanels would be involved.

  • RE: Paralleling analog switches to lower on-resistance

    I would like to refine the second part of my inquiry.  I am using an ADG1409 to route one signal (connected to common “D”) to different destinations.  I only need two destinations at the present.  The other two “S” outputs – can they be left unconnected…
