What are the differences between the ADPD4000 vs the ADPD4100 regarding performance/advantages/features.

Thanks

Hi, 

I am considering to use ADPD4000 in our product and mainly interested in the differential pair configuration when connecting photodiode (PD) to input pins of ADPD4000.

According to datasheet, it is obviously possible to configure differential input…

Hi, 

I'm using EVAL ADPD4000Z but I have some doubts about the configuration. I used the driver provided by analogdevice on github, but I had to change the adpd functions with HAL library. I tried to read the chip_id, but I read a wrong value and I…

Good afternoon,

I need information about the Firmware or source code of this product?? Can any one help me with that.

Regards,

I'm fairly new to ADPD4000 and new in doing embedded tasks.

If I'm using an arduino nano, how do I read the values from the ADPD4000? How do I connect ADPD4000 to Arduino Nano to be able to do so?

I have an incoming ADPD4100 but I'd like to take…

The trend of PPG signal we got is going up slowly and going down quickly. The real life's signal should be going up quickly and going down slowly. Anyone know why the signal is different from the normal blood wave form?

the normal one should be like…

Hello,

We are working on embedded NIRS sensor using ADPD4000 (or 4100 for futur use).

We decide to split measure for each LED wavelength: 

 - 550nm for heart rate measurement (HR, HR variability)

 - 660nm for HbO2, spO2 and breathing activity measures

Hello, I am trying to measure bioimpedance using EVAL-ADPD4000 but I keep failing.

If you look at the datasheet of EVAL-ADPD4000, there are IN5 and IN6 as impedance measurements.

I would like to use this to measure GSR or EDA, but there are no examples…

I’m trying to read an impedance value with ADPD4000 connected to stm32L4, but I have two problems with the reading of the fifo buffer and the execution of the code.

• About the fifo, I don’t why it does not fill or it fills up with no sense value…
