ADS1241: ADS1241数据采集不稳定,振荡

Part Number: ADS1241

ADS1241在数据采集过程中,不能稳定,总是在一个范围内波动,单片机程序已进行滤波处理还是一样,比如测量的温度实际值为25度,但实际显示总是在24.995-25.003之间波动,不能稳定,频率也不是很快,大概五分钟这样会波动一次,请帮助解决下,谢谢

  • 感谢您对TI产品的关注!
    关于你的咨询,我们正在确认你的问题,稍后回复您。

  • 你还有其他信息要分享吗?例如随时间变化的数据图等。?

    听起来这个问题很少发生,因为你说“它每5分钟波动一次”。这听起来并不像是ADC的问题。

  • 左边是时间,一秒一个数据,右边是数据

  • 这些信息不是很有用。此外,为什么要将整个表粘贴到此线程中,而不是在Excel文档中提供信息?你能把数据移到文档中来修复你上一篇文章吗。如有必要,您可以在回复中提供数据图

    关于数据,客户期望的结果是什么?我不知道他们期望什么,所以数据没有帮助

    那么,什么是“数据”呢?那是伏特吗?那么,客户实际测量的是什么信号/传感器?

    你能提供客户系统的示意图吗?

    他们使用的寄存器设置是什么?

    客户尝试了哪些故障排除步骤来诊断他们的问题?
