Part Number: AFE4404EVM Other Parts Discussed in Thread: AFE4404 , Hello, I am wondering if the AFE4404EVM comes with the PPG device of AFE4404 or if I need to buy them both?
Part Number: AFE4404 Hi!
I try to use short LEDs impulses to save power. Sample and hold time about 30us.
With LEDs it works fine. This is example of my registers for one of LEDs All in 4MHz clocks. Looks that work fine.

Part Number: AFE4404 Hello,
has TI performed clinical research that could provide the coefficients for SpO2 curve calibration, similar to what Analog Devices (Maxim Integrated) did here https://www.analog.com/en/resources/technical-articles/guidelines…
Part Number: AFE4404
Hello,
What are the mandatory steps to put the IC into Hardware-Power-Down mode?
Here are the steps expected to do the job:
0. Start MCU
1. 200ms sleep (Let the AFE's power supplies settle)
2. Configure RESETZ pin…
Part Number: AFE4404 Hi,
I've started working on evaluating AFE4404 using an external MCU. I wonder if there is a configuration tool that automatically generates all the device registers in a way that can be included in the code (something like an…
Part Number: AFE4404 Tool/software: Hi everyone,
I'm currently working with the AFE4404 connected to an STM32L471RET6 , and I'm trying to read PPG data using only LED1 and a single photodiode (SD019-141-411-G)
Problem:
The ADC_RDY pin always…
Part Number: AFE4404 Tool/software: Hi,
My setup consists of the AFE4404, the Osram SFH7072 biosensor, and a photodiode switching circuit for the SFH7072.
The SFH7072 biosensor includes two photodiodes: IR-CUT and BB.
I would like to use: - The…
Part Number: AFE4404 Hello, Let me know if you know... Is there a buffer that can store the measured values to a certain extent in the AFE4404? Also, can you tell me the hex that reads the LED and IR? Please help me...

Part Number: AFE4404 Tool/software: Dear Sirs.
I use AFE4404 in low power device. I need to reduce power consumption of LEDs.
Pulse repetition factor is 10ms
Today I switch LED on for 230us and wait 70us between switching the LED On and starting…
