Dear Alex Smith, Thank you for your valuable inputs. I'm not sure what you mean by matching requirement of these pins, can you elaborate? Does the routing signal of LA,RA and RLDOUT of these three pins required to be same length in the layout ? If you neglect the RLDOUT pin, then you will not be able to cancel out the common-mode noise injected on the body by the mains power/lights. Please see this app note for additional details: www.ti.com/.../sbaa188.pdf Thank you for the application note. Can we use any filter to cancel the common mode noise and neglect the RLDout electrode? Is it possible to overcome the common noise using filter? Let me know if required any more information.
