请教ADS1293 ECG 波形干扰太大

Other Parts Discussed in Thread: ADS1293

采用三导联的接法,采集出来的波形如下:

完全看不出来ECG波形,寄存器的配置和EVM一致,不知道问题出在哪里,请教一下各位高手,谢谢!

另外看了一下data sheet, 有两个疑问:

1. 29 pin PAD data sheet上标注的是No connect, 但是Schematic for the ECG With Bluetooth Low-Energy(www.ti.com/.../snvc112.pdf) 

    上PAD是接的地,这个有影响吗?目前没有接。

2.  R1, R2, C1 (CMOUT, RLDOUT, RLDINV pin上的)这三个器件的值是如何确定的? 目前用的是100K, 1M, 1.5nF.

谢谢!
