• RE: AD620和AD8037级联

    谢谢,我的电路是AD620+AD8037,使用ADG1611调节AD620的增益,使用ADG1611的时候存在这个270KHz的噪声,我又重新制了一块电路板,没有使用ADG1611,就没有噪声了,应该是ADG1611的原因

  • RE: Spice model for ADG1611 (quad SPST) ?

    Thanks, Michael. In my model, the ADG1211 (which is a substitute) has a single supply of +12V. This matches one of the specified modes of operation (page 5 of spec). I'm seeing about 1K of Ron in this setting.

    I want to use the ADG1611 in the real…

    Is it okay to connect the ADG1611BRUZ's and ADG1436YCPZ's Exposed Pad to Gnd?

     

    In the datasheet it states that the exposed paddle (EP) should be connected to
    Vss. The EP is internally connected to Vss and if the EP is connected to…
  • RE: Is spectral noise density (nV/rtHz) information available for ADI analog switches/muxes?

    Hi dananderson75,

    As you are using the audio band I would expect that flicker noise is present in the lower portion of the band. However as THD+N is very low in this region I would expect that the noise is low. As the SSM2402 is on a different process…

  • RE: ADG4612

    Hi,

    From a performance viewpoint, the ADG1611 has lower leakage than the ADG4612.

    However, the ADG4612 offers additional benefits in terms of being guaranteed Off without power so it really comes down to how the part will be used in system.

    If you…

  • RE: iCoupler clamp current

    Brian

    Thanks for your response. I meant to say ADUM4121 instead of ADUM1421.

    The opto-isolators in the drive provide isolation between the drive's internal high voltage electronics and the low voltage (5V) digital interface to my micro-controller. My…

  • RE: AD7760输入阻抗和噪声问题?

    对,我是想测量电阻两端的信号,并且要10M欧姆的输入阻抗,大动态范围,低噪声,能采集uV级信号,最好有增益控制。

    我根据您的建议,选取AD4897-1做buffer可以吗?选它的原因主要是因为它的噪声很低,另外我们还需要增益控制,用ADG1611控制增益电阻的选取,如附图方案一所示。

    另外方案二是用仪表放大器8429和8021做前端调理,如附图方案二所示。

    请问这两种方案哪种可行啊?具体说一说优缺点好吗?谢谢!

  • RE: 仪表运放AD620使用总结

    AD620是一款低成本、高精度仪表放大器,仅需要一个外部电阻来设置增益,增益范围为1至10,000。此外,AD620采用8引脚SOIC和DIP封装,尺寸小于分立电路设计,并且功耗更低(最大电源电流仅1.3 mA),因而非常适合电池供电及便携式(或远程)应用。

    AD620具有高精度(最大非线性度40 ppm)、低失调电压(最大50 µV)和低失调漂移(最大0.6 µV/°C)特性,是电子秤和传感器接口等精密数据采集系统的理想之选。它还具有低噪声、低输入偏置电流和低功耗特性,使之非常适合ECG和无创血压监测仪等医疗应用…
