Part Number: AFE4404 Hi.
I was changing Hz using AFE4404 EVM.
I want to freely change the Hz in code just like when I put the desired Hz into Pulse Repetition in AFE4404 EVM, the 0x00 to 0x1E register value changes.
So I'm curious about the formula…
Part Number: AFE4404 Hi.
I have a question while I was picking ppg with afe4404.
I understand OFFDAC, Gain.
But I don't know the function of the CF.
Thank you.
Part Number: AFE4404 Hi.
I was looking at the code Calibration_AFE4404.c initCalibrationRoutine() and left a question.
Can you tell me why the formula below came out?
Why do you save it in four variables using hysteresis percent: LOW_THR_HYS_LOW…
Part Number: AFE4404 Hello,
I am trying to increase AFE4404 data reporting frequency to around 60 HZ using the following public arduino code.
https://github.com/rakshithbk/AFE4404-Library/blob/master/AFE_Connect/AFE_connect.cpp
But however I tried…
Part Number: AFE4404 I have a special test mode that is need. It requires that all three LEDs be on at the same time for most all of the Repetition Interval.
The "normal" operational settings are for 100Hz at 1% duty cycle, with typical sequential sampling…
Part Number: AFE4404 Hi.
I am extracting PPG data using AFE4404.
I want to get pulse, spo2, and blood pressure with PPG data, is there a guideline or code provided by TI?
Thank you.

Part Number: AFE4404 Dear Sir or Madam We are having an issue regarding your AFE4404. We have a device collecting PPG samples from 3 channels - green (channel 1), red (channel 2) and infrared (channel 3). We have collected thousands of PPG signals and…
Part Number: AFE4404 Hello there,
We're currently looking at using the AFE4404 to drive an LED for 5us and read back a different wavelength for 10us using a PD. We're specifically looking at the intensity and decay time of the PD reading. Is the AFE4404…
Part Number: AFE4404 Hello TI experts,
My customer considers AFE4404 for their new product.
and they want a function to measure blood pressure.
Does AFE4404 can measure blood pressure? if doesn't, please recommend another IC which can measure blood…
