Part Number: AFE4900 Tool/software: Hello, I am seeing some strange behaviors with the AFE4900 - And I have been able to reproduce them with the AFE4900 EVM board. I am thinking that there are some underlying assumptions that are not described in…
Part Number: AFE4900 Tool/software: I'm using AFE4900YZT to measure SpO2 adding LED+PD module. I'd like to know if there is any the enhanced AFE module for SpO2 and roadmap for this AFE.in detail.
Part Number: AFE4900 Tool/software: Hello, Note: these settings can be saved and entered into the AFE4900 EVM as a xxx.cfg file. I am hoping that someone who has ACTUALLY USED the AFE4900 responds to this post. My configuration is as follows: LED1 - gre…

I want to use AFE4900 in my graduate program design but I can't find the full datasheet, does this chip have restrictions on college projects?
Part Number: AFE4900 Hello,
Due to layout constraints we used TX2, TX3 and TX4 - NOT TX1 - assuming that they are all configurable.
But, I am having difficulty setting this up.
Was this a mistake ?
Please advise.
Also - the AFE4900 timing calculator spreadsheet…
Part Number: AFE4900 Other Parts Discussed in Thread: AFE4960 Dear TI Teams,
One of our customer smart watch project is using AFE4900+SFH7072 for heart rate, blood oxygen and ECG detection. Their reported that there is high frequency interference when…
Part Number: AFE4900 Hi TI，
The following picture shows the application circuit of AFE4900. The first picture is the electrode input circuit. The second chapter is AFE4900 circuit.
Question 1: How is ECG lead off detection implemented? Is the register…
Part Number: AFE4900 Hi,
I am trying to collect data using 4 LEDs and one PD connected to the EVM board. I have set up all the registers in the configuration software to enable the 4th LED, but it is just showing noise in the 4th phase (named LED1 ambient…
