• AD7172-4 power supplies and voltage references

    I am using the AD7172-4 for a design that will need to measure a voltage of -2.5V to 2.5V with respect to ground (I assume the ADC must be set to in bipolar mode) where each input pair will have one node connected to ground (e.g., for the first differential…

  • AD7172-4-Eval ADC Error

    Hi,

    I've been fighting with this for weeks and not winning and I'm sure I must be missing something obvious. 

    I'm uing an AD7172-4-Eval board with an Arduino Due, but I've used the Eval+ software in simulation mode to configure the registers.…

  • the Calibration of AD7172-2

    Hello,

    Is a hardware reset required before each calibration of the AD7172-2 ?

    thanks.

  • AD7172-2 internal temperature sensor

    Hello,

    Can you tell me how do I have to set the input type (unipolar or bipolar) of the AD7172-2 to get the right temperature sensor senstivity of 477uV/K? Since no inducation is given into the data sheet. Similarly, based on Q&A answers, I learned that…

  • AD7172-4转换结果不稳定

    各位好:

          我使用AD7172-4芯片,REF+=3.3V,REF-=GND,采用Sinc5 + sinc1滤波,输出数据速度ODR=10次,参考寄存器选择REF_SEL0=00即参考为REF+和REF-,配置为差分采样模式。并且是连续采样模式。配置为24位。

         当我在AIN0和AIN1上都接3.3V时,采样的输出的值为0x00FFFFFF,并且很稳定,不会发生变化

         当我在AIN0和AIN1上都接1.8V时,采样的输出的值为0x00C1973X,其中X是一个变化值,变化范围很小,一般前后两次采样的值相差不过3…

  • AD7172-2的问题

    在使用AD7172-2进行宽量程测量出现ADC超量程错误时,根据数据手册,ADC结果应该钳位至0xFFFFFF。但在实际测试中获得的ADC输出并不是0xFFFFFF。请问出现这种情况可能的原因是什么呢?

  • About the over-range error of ad7172-2

    Hello,
    We have a circuit board designed based on AD7172-2 for wide-range measurement.
    According to the data sheet of AD7172-2,the output result of the ADC should be 0xFFFFFF when an over-range error occurs. 
    But we can’t get this value in the test.
    What…
