• RE: Re: Mux ADG1409

    Hi Theresa,

    Sorry for my bad writing... Below my answers.

    1. You say that results are good for the V and PT100 measurements but not linear for the 4-20mA.  Can you give details.

    - My results are based in Spice simulations. For PT100 and V, I'm measuring…

    rick,

      Too old to do a start up;  Why don't you do one??

    Here's another idea.   Use a REF196 (micropower 45 uA, DIP) to regulate the 9V down to 3.3V

    and then use an AD8237 on an adapter board.

    Maybe you'll get six months out of a battery?…

    Hi Inayath,

    Actually you can modify the CN0295 reference circuit to fit on your design. Are you going to build this on PCB board? Below is a simple circuit but feel free to add/remove or modify it based on your needs i.e. Voltage drive.

    Hi again Ali,

    Considering your configuration, I think the AD627 might be a possible candidate for you. It will work with input voltages up -0.1 of the negative rail. It has relatively low noise, low offset and consumes very little power. If you do consider…

  • 仪表放大器AD8237为什么线性很差?

    设计电路过程中经常用到仪表放大器,之前用了AD627,单电源工作时,一般价格的线性很差,后挑选军用级别的(价格40多元),线性才能得到保障。后来设计别的电路时用到了AD623,单电源工作,经过线性还是很差,不能满足要求,经换双电源工作并选择TI的INA128后,线性明线提升。经过供应商推荐,使用AD8237做仪表放大器后,经过测试,线性还是得不到保证,经过测试,误差很大,不知道问题出在什么地方。
