Hello TI team,
I am working on an SpO₂ application using the AFE4400, which typically requires a photodiode, red LED and an IR LED. Could you please suggest suitable red and IR LEDs that are compatible with the AFE4400…
Part Number: AFE4400 Tool/software: Hello，
The customer is using AFE4400 and cannot read blood oxygen values. The customer conducted chip exchange verification, and the problem was transferred with the chip. The following is a schematic diagram. Please…
Part Number: AFE4400 Other Parts Discussed in Thread: AFE4500EVM , AFE4500 Tool/software: When I collect PPG signal using AFE4500EVM, I can see a noise component at 40Hz in frequency domain.
In particular, when I got a signal using the combination of IR-cut…
Part Number: AFE4400 Tool/software: It automatically diagnoses error 0x1030, I cannot understand why the photodiode is short circuited and open circuited again, and bit12 indicates

I would especially like to know about Question 1.
I don't want to damage the IC by mistake.
I would like to know if there is any misunderstanding in what I am thinking.
In particular, the phrase "Can be connected to the port pin of an external microcontroller…
