  • Problems with AD7091

    Good day! I have several questions about AD7091.

    1) How to make a software reset correctly? We are thinking that documentation is written not so accurate in some points.

    2) What exactly will be with AD7091 if we won’t do software reset?

    3) Additionally…

  • AD7091-R8

    目前用AD7091-R8设计一款8路电压采集模块,AD7091的模拟输入范围是0~Vref(2.5V)。

    需要采集的目标电压是0~10V,计划使用运放ADA4807(替换ad8032)在前端设计电压跟随器。

    在运放的正极使用分压电阻,使正极的输入把输入分压到0~2.5V,运放负极接输出,形成电压跟随器。

    由于运放的输入阻抗是45兆欧,分压电阻是否取K级即可?

    如果不想使用电阻分压的方法来调节运放正极的电压,前端是否有可选的芯片完成增益(0.2)调节功能(AD8475是否适用)?

    是否有比AD7091…

  • RE: AD7091 - Software Reset

    Hi Christian,

          The AD7091 recommends to have a software reset after the first power up. It is not necessary to have the software reset after the part wakes up from the power down by driving the CONVST high then a new conversion can be initiated by driving…

  • AD7091 SPI mode

    Hi

    I would like to read data from AD7091 using ARDUINO MEGA 2560.

    As I am new to SPI ADC & Arduino,

    My doubts : 1) Which mode SPI to be used for AD7091.

    2) is there a sample code in C or VHDL for AD7091 ?

    Any help shall help me to make progress…

  • AD7091 - connection to /CS pin

    Hello:

    With respect to the /CS pin on the AD7091, is this basically an output enable (e.g. can I always leave it on if I want to)?”

    Can this pin be tied to ground indefinitely?

    Any input or feedback is welcomed and appreciated!

    Thanks!

    Paul

  • AD7091 max analog input range ?

    Hello,

    I plan to use AD7091R-8  with VDD and Vdrive to 3.3V and use embedded 2V5 voltage reference.

    some of the circuits i want to measure use drivers with low impedance and powered with 5V. Even if I can adjust operating scale of these circuits to 2…
