    您好、Wayne、

    在我看来、每个器件的左右通道仅使用双二阶1、而其他滤波器设置为默认值。 根据您提供的系数、下面是双二阶1的响应：

    这是所需的滤波器响应吗？ 如果您想去除数据中的直流分量、则需要在其他两个比额表中的一个中实现高通滤波器。

    最棒的

    Zak 您好！

    此外、我们能否使用第1页的抖动控制寄存器寄存器26来校准客户 ADC3110器件的直流偏移？

    您好、Wayne、

    是的、但更有可能的是、该抖动寄存器没有校准您所看到偏移的分辨率、因为它只能以+/-15mV 的阶跃进行设置、这可能已经大于您需要校准的直流偏移。

    最棒的

    您好、Wayne、

    我对不同的滤波器选项进行了一些测试、以消除直流组件。 我发现最好将可编程 IIR 滤波器用作 HPF。 随附的是我的测试结果：

    请注意、这还讨论了差分输入的空闲音调以及高通滤波器选项。
