I am using the AD8232 in a Bluetooth Low Energy Heart Rate Monitor Application. I am currently in the process of hardware verification of the prototype boards. I am currently using two resting ECG Electrodes attached to myself to monitor the heartbeat. I am using the AC Leads Off Detection Mode. When I connect the ECG Electrodes to myself, I was expecting the LOD+ signal on the AD8232 to transition from the Logic High State to the Logic Low State. What I am observing is the LOD+ signal toggling at approximately 60 Hz. Is this the response I should be seeing from the LOD+ signal? If not, why is it toggling instead of transitioning to Logic Low State and then remain at this state until an Electrode is removed?
Your help would be greatly appreciated.
