AFE4490: SPO2 Saturation algorithm

Part Number: AFE4490

Hi all,

 i purchased AFE4490 IC  and Integrate with my controller .

I Collect the data and processing it and draw as a waveform  then  i calculate Pulse Rate and SPO2 Saturation values using algorithm.

-----> Spo2 Saturation values are wrongly calculated randomly .

(i.e) some fingers it showing correct value some fingers showing wrong value. in simulator its working fine.

 ----> waveforms having wandering issues.

is there any sample code for this spo2 calculation?

  • Hi Arun,

    Sorry to say, we don't have sample code for the SP02 calculation since it changes from customer to customer, also it will be platform dependent.
    For consistent result you may try some signal processing techniques to remove DC wandering.
