仪表放大器电路以其高输入阻抗、高共模抑制比、低漂移等特点在传感器输出的小信号放大领域得到了广泛的应用。
Instrumental amplifiers with high input impedance, high CMRR and low drift are widely used in the small signal amplifying field.
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.
