此肌电放大器的前置部分采用共模驱动，以达到提高其共模抑制比和输入信号的动态范围，以及抑制工频干扰等作用，并采用线性光耦隔离。
Apart from employing the linear optocoupler isolation, this EMG pre-amplifier uses the boost to enhance the CMR and the input swing and reject the industry interference.
输出宽度可通过延时在一定范围内调节，消光比达50000倍，透射率大于90%。
Moreover, the output pulse duration can be adjusted within specified range, the extinction coefficient reaches 50000, and the transmittivity is higher than 90%.
