ADS1298: ADS1298

hi,

   Using the ADS1298R to achieve respiratory function, encountered the following questions:
1. We are currently mainly confused: Schematics R24 and R27 are not attached at present. Use IN1P/IN1N as the respiratory wave acquisition channel and the data is normal. At the same time, it will affect other ECG data acquisition (IN2~IN8). The chest lead V1 is not collected. ;
       Will the respiratory wave and ECG acquisition be performed at the same time? What is the method of implementation?


2. Please help review the attachment. Is there a problem with the schematic design?

    Hello Eric,

    Thank you for your post!

    The respiration modulation clock should not show up as noise on the other channels due to the digital filter rejection.

    The schematic looks fine and there should be no problems taking ECG and measuring respiration at the same time using this configuration.
