您好,
坦白说对于肌电(EMG)信号的测量我不太了解,对于ADS129x的应用更多关注的是ECG(心电)和EEG(脑电)的测量。
心电信号(Lead I 、Lead II)应该是差分信号的测量,或者(Lead V1 ~Lead V6)是以WCT信号为参考输出的,具体查看ADS1293 datasheet 典型应用接线图。而ADS1299是没有集成WCT电路的。
关于EEG信号的测量,建议您关注ADS1299EEG-FE用户指南的第7部分 EEG Specific Features,ADS1299EEG-FE用户指南:

看下面E2E论坛帖子的回复,ADS129x是适合 ECG, EEG, 和 EMG信号的应用的:
