ADAS1000 True Gain

Hello,

 

I have been reading the datasheet of the ADAS-1000 and for me it is not clear which is the gain of this component.

You have these gains in the datasheet:

GAIN 0 = ×1.4, GAIN 1 = ×2.1, GAIN 2 = ×2.8, GAIN 3 = ×4.2

 

But normally in a ECG instrumentation path, the gain is in order of thousands. Maybe I am missing something in the datasheet.

 

Also for me it was really strange that the minimum Electrode Input Range in the datasheet is 0.3V. And normally, the ecg voltage of an electrode is like 4mV maximum.


Thanks for your help in advance.
