在芯片的手册讲到相关的内容:
Output filter — The ferrite EMI filter (see Figure 30) should be placed as close to the output terminals as possible for the best EMI performance. The LC filter should be placed close to the outputs. The capacitors used in both the ferrite and LC filters should be grounded.
这里好象没有其他的细述,EVM 板的手册也没有介绍,不过在TPA3113D2的手册介绍得详细一些,更详细的计算 可能得找音频滤波和噪声相关的专业资料了。
