• 关于ad620与ad627适合的放大的信号频率范围。

    ADI的大佬:

                 您好,我想询问一下AD620与AD627两款产品各自适合的信号输入的频率范围。

  • 关于AD627在4-20mA检测电路中的问题

    您好,我在查阅AD627的技术手册时,关于该技术手册中的图524-20mA的检测应用电路)我有一些问题,图中的电流环是否需要与AD627共地?

    因为我在同样是仪器放大器AD8420的应用电路资料中,发现该应用电路笔记中的图四(同样是4-20mA的检测应用电路),二者是共地的。

    那么,关于仪表放大器在4-20mA电路中的应用,到底应不应该接地呢?

    我个人理解是应该共地的,否则仪表放大器相当于在测量浮空源,将没有为偏置电流提供返回路径。

    Hello

    I have succeeded to make it working with a RC filter after the output of the AD627. This one is a real exceptional amplifier. Thanks to everybody for the idea about the RC.

  • 仪表放大器AD627输出异常

    使用AD627对外部微弱信号进行放大,信号由信号发生器发出,设计电路如图1所示。外部输入信号的频率为400Hz±20Hz,当放大倍数为500时,输出还算正常,但也有漂移。

    但当把放大倍数调到800,1000以后,AD627的输出波形异常,开始向正电源方向偏移。图2为放大器放大倍数为500时的波形。

  • AD627: Minimum Vref for single supplies.

    Hi,

    What is the minimum Vref for single supply configuration?

    The following is figure 39 from the AD627's datasheet.

    The minimum Vref curve is greater than 0V for Vin(-) <3.2V, but I can't find its exact value. Also, what happens if I force a…
