• RE: What is AD7190 minimum AVDD voltage? The data sheet shows 4.75Vdc.  Can I use 3.3Vdc as AVDD if I am using 2.5Vdc reference?

    Hi,

    The evaluation board is used for AD7190 and AD7192 part. The AD7192 can operate from 3V to 5.25V. So the option for 3.3V is for AD7192 part.

    Thanks,

    您好,我使用你们公司的AD7192,采集的电压值,但是根据你们双极性的公式算出结果误差有0.1V左右,有点大,怎么修改了?并且寄存器中的失调寄存器与满量程寄存器怎么使用了?比如失调寄存器的值是0X800158,满量程是0X566530,怎么使用这个数了?

    工程师您好:

          我是用的你们公司的AD7192,AINCOM口输入2.5V,AIN2输入电压,REF输入5V,双极性输入。我输入的电压为0到5V(每0.5v取一个值),但是根据公式计算得到的误差大概有0.1V到0.01V不等的误差,这个不知道是什么原因?(我的模式寄存器配置为0X002040,模式寄存器为OX0C2880),并且这个ad的失调寄存器与满量程寄存器中的数值怎配合数据寄存器使用呢?谢谢

          谢谢。

  • RE: AD7193 Driver with Raspberry Pi

    the AD7192 driver supports 4 ADCs : AD7190, AD7192, AD7193 & AD7195;

    so, you need to use that driver for AD7193 as well ;

  • RE: What order has the delta sigma converter in AD7192 ?

    Hi Kenneth43,

    The AD7192 uses a fourth order modulator. The filter is either sinc3 or sinc4 - you can choose which option to use via the SINC3 bit.

    The AD7192 uses standard sinc3 and sinc4 filters. Review the excel file on the AD7192 product page …

  • RE: AD7192 x2 and x4 gain


    Hi,

         The AD7192 can still function at  gain of 2 and 4. When Vref is 2.5V, the AD7192 does not guarantee to meet the specification at gain 2 and 4. These gains are not specified on the datasheet.

  • RE: AD7192 driver install problem

    Hi,

    Yes, that is correct. Make sure that you have this patch staging: iio: adc: ad7192: Added devicetree support. · analogdevicesinc/linux@447e706 · GitHub, which enables devicetree support for the ad7192, in your tree.
