AFE4960: AFE4960 Electrode testing

Part Number: AFE4960

Tool/software:

Dear TI Support Team,

We are currently developing a project that incorporates the AFE4960YBGT for ECG signal acquisition. As part of our validation process, we aim to test the device's built-in lead break detection capabilities to ensure reliable operation in scenarios where electrode disconnection might occur.

Upon reviewing the AFE4960 datasheet, we noted the presence of both DC and AC lead biasing features designed for lead on/off detection and impedance measurement. However, we are seeking more detailed guidance on effectively testing these functionalities.

Could you please provide or direct us to any reference materials, application notes, or evaluation procedures that outline the recommended approach for testing the lead break detection features of the AFE4960YBGT? Specifically, we are interested in:

  • Configuring the device for lead-off detection.

  • Simulating electrode disconnection scenarios.

  • Interpreting the device's responses to such events.

Any assistance or documentation you can provide would be greatly appreciated.

    Hello Harijith,

    I would recommend looking at the other resources in the Secure Resources folder for the AFE4960 -- specifically, "Video 4" demonstrates how to test lead-off detection using the scripts included in the EVM software, as does the User Guide (note: DC lead off detection is referred to as "IDLE" mode in both).

    Regards,

    Payton
