TIDA-01580: TIDA-01580 ECG circuit.

Part Number: TIDA-01580
Other Parts Discussed in Thread: AFE4900

Hi, 

I doing a test about a ECG sensing of custom circuit and electrodes. (reference, TIDA-01580 circuit)

However, during the test, a question arose.

Is there a way to use electrodes with relatively high resistance by changing the value of the circuit of the ECG part?

We would appreciate your reply after checking.

Thank you.

Regards.

    It depends on what kind of electrodes you are using.

    For dry electrodes, the output impedance is higher than the wet electrodes. The ECG front-end circuit will change accordingly. I suggest looking at the latest datasheet of AFE4900 for the same.

    I can not share it here because the datasheet is under restrictions. You can request the full datasheet on this link: https://www.ti.com/product/AFE4900
