• 关于修改AD7176-2采样率的问题

    请问我需要修改AD7176-2的采样率从10sps到10Ksps,采样率尽可能多的变化,需要怎么做?通过修改主时钟频率来改变采样率吗?

  • AD7176-2

    Hi ,

     

    I have planned to use AD7176-2 ADC in our project to read thermocouple, thermistor, RTD , Voltage , Current and strain gauge sensors. I am finding it hard to fix what is the conversion time and settling time.

     

    I will be using one channel…

  • AD7176-2 单次转换结果不正常??

    最近有个项目用到AD7176-2,

    我采用官网提供的例程,连续转换方式时,采集到的数据,与实际波形比对,一致性很好

    当我尝试单次转换模式时,设置ADCMODE 寄存器0x8010;SETUPCON0寄存器设为0x0020,

    通道0-3均使能,

    得到的转换结果不随输入值变化,始终是0x7FFFFF左右的数值,而且通道号始终为0。

    经反复试验,依旧如是

    不知原因为何,恳请赐教

  • AD7176-2零输入时候,AD的转换结果

    咨询下AD7176-2的疑问

    当输入为零的时候,读取到的AD 24位输出数据是0X800000(二进制最高位1)么

  • AD7176-2 : XTAL1 pin

    Hello,

    I have a question about the XTAL1 pin of AD7176-2.

    I will use the internal clock of AD7176-2.

    And, I do not use the clock output from AD7176-2 to the outside.

    In that case, how should I process an unused XTAL1 pin?

    Best Regards,

    Mr.K

  • AD7176-2: FAQs

    I don’t see a reset pin – how do you reset the ADC?

     

    The AD7176-2 does a power-on reset but can also be reset by writing 64 1’s to
    the part over the SPI interface.

  • AD7176-2 split rail decoupling question

    Using 2.5V for AVDD1 and  -2.5V for AVSS

    !: Do REF+ and - pins need to be decoupled to AVSS or AGND.?

    2. Should an input amplifier ref be AGND or AVSS? (Its rails will either be +/-5V or +/-2.5V)

    3. Should RCAPA pin be decoupled to AGND or AVSS?

  • AD7176-2 RDY

    Hello

    Could you teach me about the high width of AD7176-2 RDY at single conversion?

    I think that high width of RDY include scan time ( 20us) + settling time.

    Is it correct ?

    My customer test this at below condition.

    (My customer thought that high…

  • AD7176-2 reference code

    Hi Experts,

    I want to learn AD7176-2 for high precision applications.

    Can I get the reference code? or some demo code just like UG-478 and CN0310?
