Dear：
在TAS5421的数据手册中提到可以输入单端信号：原文如下：
When using a single-ended audio source, ac-ground the negative input through a capacitor equal in value to the
input capacitor on the positive input, and apply the audio source to the positive input. For best performance, the
ac ground should be at the audio source instead of at the device input if possible
我这样处理对吗？如下：
谢谢！
