Part Number: AFE4400 Tool/software: Hi, we are working on AFE4400 with SFH7070 for a PPG measurement on wrist. is there any gain setting recommendations and algs (2 green LEDs)?
thank you!
Part Number: AFE4400 Tool/software: I am looking into sensors which can measure SpO2, Heart rate, HRV and respiratory rate. Will this sensor be useful for these applications or are there any other better ICs. I want to use this sensor for a wearable which…
Part Number: AFE4400 Tool/software: D ear TI Support Team,
I am using the AFE4400 in my prototype design and have downloaded its footprint for PCB layout. However, I would like to verify the accuracy of the footprint against the official TI land pattern…
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 Hello, community!
I'm currently working on a project involving multiple AFE4400 devices to capture PPG waveforms. However, I've encountered a significant challenge with SPI communication. While a single AFE4400 on the bus operates…
Part Number: AFE4400 I am using AFE4400 for getting PPG signals from the artery. W e are getting the attached graph in Arduino ide by using below code (graph and code attached).
Please let me know how can measure PPG signals correctly using Arduino…
Part Number: AFE4400 The LED used in this case is SFH7072 OSRAM. Can you please help with the code where there will be perfect PPG signal acquisition. Do let me know about noise filtering as well. Thank you.

Tool/software:
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…
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…
