Part Number: AFE4900 Other Parts Discussed in Thread: TIDA-01580 Dear manager.
Hi.
I am currently testing ECG signal measurement. The circuit was constructed using the AFE4900.
However, I designed analog GND and digital GND into one. TIDA-01580 used…

I checked the e2e post but it is different from my question.
I get the raw data usually. but sometimes ppg signal is inversion.
I attach the file, so please check it.
Regards.

I measure a person's ppg signal with afe4900.
Normally, It is measured like the picture 1.
but, sometimes I can get inverted PPG signal like the picture 2.
And when I measure the 4ph signal, the Green PPG signal is normal. but…
Part Number: AFE4900 Other Parts Discussed in Thread: TIDA-01580 , Hi,
I made a dry electrode and testing is in progress.
However, it is difficult to set the gain because the DC offset is different for each person.
I tried using a high pass filter, but…
Part Number: AFE4900 Hello, manager.
I am testing a Red and IR PPG sensor on my wrist using the AFE4900 and SFH7072.
However, there is a problem that does not well sensing if i again measure the signal that sensing well.
I am testing while increasing…
Part Number: AFE4900 Other Parts Discussed in Thread: BQ25120A , TIDA-01580 , Hi I am designing a product with the AFE4900 and other 0.4 mm pitch DSBGA packages (BQ25120A). These packages require a 0.23 mm pad, which is quite challenging for the PCB manufacturer…
Part Number: AFE4900 Other Parts Discussed in Thread: AFE4400 , HI Ti team:
What are the functional and performance differences between afe4900 and afe4400? Do you have any comparative documents
Thanks

Part Number: TIDA-01580 Other Parts Discussed in Thread: AFE4900 Hi,
I have two working versions of the TIDA-01580 design running the default TX firmware, and an external BLE dongle that reads the data. I'm testing both devices, mostly focusing on the…
Part Number: AFE4900 Other Parts Discussed in Thread: TIDA-01580 Hello.
I testing a PPG sensor of AFE4900.
I am using a PPG sensor to measure SpO2 on wrist.
However, there is a difference in data between IR and Red, so the SpO2 value cannot be accurately…

Hi
I am trying to receive an ECG signal using the AFE4900's FIFO.
However, it is difficult to receive ECG signals.
The ECG electrode is being tested using copper and the following signal is received.
(10000 data = 10 seconds…
