• the Calibration of AD7172-2

    Hello,

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

    thanks.

  • 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…

  • 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…

  • AD7172-2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?

  • How to make burnout currents enable in AD7172-2

  • 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).

  • AD7172-2 SPI communication error

    Hi,

    I've been working with the AD7172-2 for almost two years now and it have been working.

    I'm now redesigning the prototype board to fit the final product. Schematic is exactly the same and board layout around the AD7172-2 is almost exactly the same…

  • AD7172-2 接口寄存只能配置为0x0000

    您好,在使用AD7172-2时,对ad7172进行初始化配置时发现,ADC模式寄存器、通道寄存器、设置寄存器、滤波寄存器、都可以正确配置,唯独接口寄存器一写入非0x0000值后,再读取其它各个寄存器的值发现都不再是原先写入的值了,感觉有点奇怪。如果配置接口寄存器位0x0000,所有的寄存器都是对的,一配置其它值,再读取ID寄存器都是错的。使用的是ADI官网的驱动。百思不得其解。请工程师是试一下看看,万分感谢。

    如果不配置接口寄存器,在使用多通道时就无法让状态寄存这个字节附加在数据寄存器的后面,这样就不知道数据时哪个通道的…
