AFE4410: Help with "Break-in" phenomenon with AFE4410 based heart rate sensor

Part Number: AFE4410

Tool/software:

Hello,

We have a heart rate sensor based on the AFE4410 and have noticed a sort of "break-in" period where the sensor has worse performance compared to after it has been used for around 72 hours or so. It seems like to me there is some mechanism that is causing lower SNR after the device has been produced but is improved as the sensor is used initially. I was wondering if the team has any experience with issues like this?

Thanks,

Tyler
