Original question:

ADS1298R: Wiring respiration leads

ADS1298R: ADS1298R: problem with respiration channel

AlexHome
Intellectual 990 points
Part Number: ADS1298R 
I connected the respiration channel to RA and LL (II), as described here: https://e2e.ti.com/support/data-converters/f/73/t/762505
And on the respiration channel I observe a signal repeating II (~1mV), but with a smaller amplitude (~0.2mV). What could be wrong?

    Hi Alex,

    Please visit the ADS129x FAQ page for some helpful documentation on using the respiration feature in the ADS1298R. The ADS1298RECGFE-PDK User Guide also has some example schematics and software settings, as well as equation examples to illustrate the expected baseline and peak-to-peak respiration amplitude.

    Best regards,
