For improving the anti-interference ability of the amplifier, the Differential Mode input with high common mode restraining technology is adopted in amplifier circuits.
为提高放大器的抗干扰性能，放大器电路采用共模抑制能力很强的差模输入方式。
This type of interference is induced equally into both differential inputs, and therefore appears as a common-mode signal.
这种类型的干扰一并来到两个差分输入端，因而出现一个共模信号。
