• AD7785 Digital Interface

    We are using the AD7785 on an SPI bus with two other ADCs. Our desire is to initiate a conversion with a write to the device, and during the AD7785 conversion time (which could be long depending on the final selection), we would like to use this bus to…

  • Problem installing AD7785 Eval Board software on Windows 8.1

    I disabled the Unsigned Driver installation then installed the AD7785 Evaluation Board software and rebooted. But, no matter what I do the board is recognized as an Unknown Device. Any help is appreciated.

    Thanks, Dave.

  • Request AD7785,AD7193 Eval board Labview code.

    Hi ,

    I've an evaluation board "EVAL-AD7785EBZ" and "EVAL-AD7193EBZ"

    I would like to have Eval board LabVIEW code or Labview SPI library for study how to communicate with ADC ICs via SPI ..

    Can you help sent me that ? Thanks…

  • How to configure a 3 RTDs using the AD7785

    Hi,

    We are considering a circuit that was used AD7785.
    You want to configure 3 pieces to connect the RTD(AIN1 (+/-), AIN2 (+/-), and AIN3 (+/-)) of the 4-wire sensor.

    (excitation current source is common to three)

    Is it possible the connection of the…

  • AD7785 digital filter design

    Hell all,

    Can anyone explain the numbers for each column shown on the Setup Table in attached document? What do those constants represent?

    Thank you so much for the help in advance.

  • RE: ADS1220 pin compatible substitute from ADI

    JoonasH,

    Unfortunately I don't think we have anything exactly pin compatible and the only parts we have that are close are in the TSSOP package version.  Take a look at AD7785, AD7793, AD7799 and see if those wouldn't make sense with small modifications…

  • RE: ADI有没有测量1~1500R电阻方案

    用LCR表那种测阻抗的方法,来测动态范围1000左右的纯阻值,有点浪费了的。

    建议用类似电子称/NTC/PT100的方案,最为简洁的就是选用带恒流源输出的ADC(或用运放+基准外搭恒流源),像AD7124-4,AD7192(RMS Noise低),AD7785

  • RE: Precision sample timing using AD779x converters

    I just downloaded the spreadsheet at http://www.analog.com/media/en/engineering-tools/design-tools/AD7785-AD7792-3-4-8-9_filter_model.xls and it still contains the incorrect formula in cell D12. This spreadsheet should be fixed!

  • RE: AD7793: REFIN pin draws 168 uA - is it broken?

    Hi AndreasKi,

    How come the schematic you attached shows a AD7785 being used, instead of the AD7793 which you mentioned?

    Assuming that it is just an error, and you are indeed using the AD7793, may I refer you to the sample circuit shown in page 29, figure…
