AFE4404: How to write AFE 4404 Offset Calibration routine

Part Number: AFE4404

I'm using TI AFE4404 with Osram SFH-7050 in 3-LED mode. Is there any reference how to design calibration routine? It looks like PD saturates to (1048460)decimal for Red, Green and IR led measurement.

Thanks in advance

    Hi Arpit,

    You can download the source code for the AFE4404EVM's firmware as it contains the document for the calibration routine.
    Once you get the source code , the document will be in the installation directory.
    If default installation path is chosen, the document will be at.
    C:\AFE4404EVMFWSRC-v1.4\AFE4404EVM_FW_SRC-1.4_release\Documents\AFE4404_Calibration_Conceptual Visualization.pdf.

    Regards,
