Part Number: ADS1292R

Tool/software:

I am using ADS1292R as 2 lead ecg(LA & RA) and respiration sensor. How do I bypass the third lead (RL) and make necessary changes in the register values. I want to extract both ECG and Respiration

    Hello Pallavi,

    Thank you for your post!

    In short, using only two electrode leads without the RLD means there is no established DC bias voltage on the body. You will then need to AC-couple the ECG inputs (CH2) as well as the respiration receive channel (CH1).

    For example register configurations, please refer to the ADS1292R data sheet and related EVM User Guide.

    We also have an FAQ page on E2E which links many common questions, application notes, and training videos regarding ADS129x devices. Please check them out here!

    Regards,

    Ryan
