Other Parts Discussed in Thread: AFE4400

Dear TI experts,

I am going to promote AFE4432 to my customer. They want to measure which is similar to SpO2

and they already choose the LED and photodiode module.

Could you check that these components are compatible with AFE4432?

and one more question ; Can I adjust the brightness of the led which is connected to AFE4432?

Please check this issue. Thanks.

Best regards,

Hi,

Dear Yang,

Thank you for your support.

I wish that another engineer support this issue if you can.

and I did not know that AFE4432 needs NDA.

How about AFE4400? it is more simple device, do not need NDA.

Can I connect those 2 LED and photodiode to measure SpO2?

one more question ; what is the difference between SpO2 and pulse oximetry?

Best regards,

Chase
