能谱仪上用的线性放大器，除了有足够的放大倍数外，还须有良好的线性和宽广的动态范围。
The linear amplifier on the spectrometer, besides it has the enough enlargement factor, and needs the good linearity and the broad dynamic range.
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.
