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 Hi.
I'm measuring PPG on my wrist with AFE4404.
I look at the datasheet, 2A to 2C is LED1VAL, LED3VAL, LED2VAL.
But if you look at 2D to 2F, you get the value of ambient.
What is ambient?
I can get the value by lighting…

I'm measuring on wrist, but there's a problem that everyone has so much difference.
Some people come out well, some people don't..
Does AFE4404 have AGC function? Or do you have an…
Part Number: AFE4404 Hi there. I need to determine the DC values of the signal, I cannot use a high pass, this phenomenon seems to be a thermal drift, some other idea to correct this situation.
Thank you so much
