Hello, I have implement the 2 electrode circuit for ADS1292R to detect ECG waveforms but the problem is that the signal is with common mode noise, so I refer to figure 47(page 50) on the datasheet of ADS1292R for applying RLD to cancelling CM noise. I just want to make sure my understanding is correct that I do not need add a third electrode for RDL input and the chip will automatically pick from the existed 2 electrodes, right? For the pin connection, I just need to connect RDLIN to RDLOUT and add 1Mohm resistance in parallel with 1.5nF capacitance between RDLOUT and RDLINV and set the the registers according the to figure, right? Thanks, Yiwen
