ADS1293: Addressing Noise Issues in Wearable ECG Monitors: Seeking Regulatory-Compliant Solutions

Part Number: ADS1293
Other Parts Discussed in Thread: ADS1294R

I have developed a 3-channel ECG monitor utilizing the ADS1293. It is functioning properly. However, as it is a wearable device, it is encountering significant noise issues, including powerline interference. Is there a solution available for this? When compared to other analog front ends (AFEs), this specific part number lacks compliance with regulatory standards. This device is intended for use by medical professionals.

Potential Solutions:

  1. Investigate the root causes of the noise issues encountered.
  2. Explore alternative AFE options that meet regulatory standards while maintaining the current design specifications.


I have examined the ADS1294R, which offers respiration measurement capabilities, a feature that aligns with our requirements. However, why is this particular part number not recommended for new designs? Additionally, could you recommend an AFE part number that offers:

  • 3 channels with a Right Leg Drive (RLD) feature
  • Respiration measurement capability
  • Noise cancellation functionality
  • Compliance with regulatory standards
  • Currently active in production
