• AD8422

    Dear all, 

    I'm testing AD8422 using EVAL-INAMP board. 

    Test set-up is the following:

    • +/-5V power supply
    • Signal generator with the following configuration: sinusoidal waveform, 134mV pk-pk, 0V offset, 100kHz. 
    • AD8422 gain set to 5,5 (Rg=4,4kOhms),
    • AD…

    AD8422设计放大100倍,+/-12供电电路,当输入超过0.1v时,供电电源出现偶次谐波,如何能消除这个影响呢?

  • AD8422

    Hi,

    I'm using AD8422 to amplify the siganl from bridge circuit.

    when I/P voltage 5V,RG = 301 ohm i see the output amplified linearly.

    for 0KG on bridge ckt = 0.3824V

         1KG                 = 0.5089

          2kG   = 0.6350

           3Kg = 0.7611

    But for RG = 100 ohm

    0KG = 2…

  • Can I replace AD620 or AD8221 directly with AD8422 in my circuit?

    Can I replace AD620 or AD8221 directly with AD8422 in my circuit?

     

    AD8422 is only available in the High-Performance Pinout which was introduced by
    the AD8221, so a board layout change is required to switch from AD620 to
    AD8422. AD8422…
  • RE: AD8421 performance considerations

    Note: AD8422 has even a much more flat frequency response then AD8421 -> If smaller bandwidth of AD8422 is OK -> it will be the better solution.

  • evaluation board and a spice model for the AD8422 to help me accelerate the design and verification process?

    Is there an evaluation board and a spice model for the AD8422 to help me
    accelerate the design and verification process?

     

    Yes.  The AD8422 is compatible with the EVAL-INAMP-82RZ (SOIC version) and the
    EVAL-INAMP-82RMZ (MSOP version):…
  • Is the AD8422 intended for single-supply applications

    Q

    You mentioned rail-to-rail output. Is the AD8422 intended for single-supply
    applications?

    A

    The AD8422 works on a wide range of supplies from +4.6V single supply to ±18V
    dual-supply, providing excellent power-savings and high-precision performance…

  • EMI filtering using AD8422 for RTD measurement

    I use the AD8422 for RTD sensor measurements and I have problems with EMI filtering. The resistor bridge is used for signal condition of RTD measurement, and this method is described in the application note (Linear Technology AN43). This circuit uses 3…
