• 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.…

  • 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…

  • About the time until the conversion result output of AD7172-2

    Let me ask you about the time it takes for the AD7172-2 to get results in single conversion mode (the time it takes for the / RDY pin to go down).

    All used with default settings (250Ksps, CH0 only ON, SIN5 + 1,SING_CYC = 1).
