HI
I am using afe4404 with sfh7072 getting good data on finger, using same register setup start to working on wrist it works only when i wear the strap very tightly.My question is whats the distance i need to provide between sensor…
Part Number: AFE4404 Other Parts Discussed in Thread: AFE4432 Hi.
I am doing PPG test using AFE4404.
I was watching Chip Applications, and I got a question, so I'm asking.
Check out the AFE4404 chip applications.

Part Number: AFE4404 Hi.
I was looking at the Calibration_AFE4404.c code and I had a question.
In Calibration_AFE4404.c, it is declared BLOCK_SIZE = 8, BLOCK_SIZE_BITS = 3.
Is there any problem if I change it to BLOCK_SIZE = 16, BLOCK_SIZE_BITS…
Part Number: AFE4404 Hi, I am developing nRF52832 and AFE4404.
I am measuring PPG for three colors, IR, Green, and Red at the same time.
Green and IR come out clean, but Red always has noise and PPG waveforms are hard to see.
The picture below is…
Part Number: AFE4404 Hello support:
The Vf of UVC LED will be over 8V.
AFE4404 can not drive high voltage LED.
I will make an external high voltage LED driver circuit.
But I want to sync LED driver ciuit.with AFE4404.
How could I sync ?

Hello Nishi,
Section 8.3.5 in the datasheet mentions the I2C protocol to be followed to communicate to AFE4404.
You can read back the data from AFE4404 to check if the data is really written or not.

Part Number: AFE4404 Hello Praveen Aroul ,
I have some questions regarding AFE4404. I am using it with ESP32 on Arduino IDE and SFH7072 I have write a code wrt these sensor but don't understand how to correctly deal with the register setting. Need help…
Part Number: AFE4404 Hi,
I am running into some trouble with the initial calibration of each LED. Right now, I am using the Ambient phase sampling as my reference for ambient cancellation for all 3 LEDs.
I run the initCalibrationRoutine() before startup…
Part Number: AFE4404 Hello,
I am building an application based on the AFE4404. For the proof of concept, we are interfacing the AFE4404 with the Arduino Mega. We are able to initialize and communicate with the AFE4404 but the ADC data we read seems…
