I would especially like to know about Question 1.
I don't want to damage the IC by mistake.
I would like to know if there is any misunderstanding in what I am thinking.
In particular, the phrase "Can be connected to the port pin of an external microcontroller…

What I want to do: I want to set the AFE4490 datasheet Figure 116. LEDCNTRL: LED Control Register (Address = 22h, Reset Value = 0000h) and control…
Part Number: AFE4400 Hello, community!
I'm currently working on a project involving multiple AFE4400 devices to capture PPG waveforms. However, I've encountered a significant challenge with SPI communication. While a single AFE4400 on the bus operates…
Part Number: AFE4400 Tool/software: If the photodiode is in a single-ended input configuration, how should it be connected to the INM and INP pins?
Is the connection method for the photodiode as shown in the picture below possible?
Thank you.
Part Number: AFE4400 The LED used in this case is SFH7072 OSRAM. Can you please help with the code where there will be perfect PPG signal acquisition. Do let me know about noise filtering as well. Thank you.
Part Number: AFE4400 I am using AFE4400 for getting PPG signals from the artery. W e are getting the attached graph in Arduino ide by using below code (graph and code attached).
Please let me know how can measure PPG signals correctly using Arduino . #include…
Part Number: AFE4400 Other Parts Discussed in Thread: AFE4490 , AFE4403 , AFE4432 , AFE4460 Dear TI experts,
My customer considers IC to measure SpO2, and have few questions about it. Could you check the questions below?
1. Is there any IC which can measure…
Hi,
Please compare the schematic with the EVM's schematic design.
E.g.
Blue mark - C36 might be optional, but it's okay to keep there for test and flexibility.
Red mark - please double check to improve. Are ANA_SUP and DIG_SUP sharing the same…
Part Number: AFE4400 Other Parts Discussed in Thread: AFE4404 Hello,
I am designing a product with an SPO2 and MHR sensor. I will control it with an ESP32 through I2C/SPI (I am lacking GPIOs).
I will use a DB9 8000J sensor ( https://www.nonin.com/products…
