    TI Thinks Resolved
    Part Number: AFE4432 Tool/software: Hi, We could not find the pin description and application information for AFE4432 in the datasheet https://www.ti.com/lit/ds/symlink/afe4432.pdf?ts=1717893495862&ref_url=https%253A%252F%252Fwww.ti.com%252Fproduct%252…

  • RE: AFE4432: what is VHR

    Hello, that is correct. You can interpret VHR as, if VHR = 1V and LED VF = 2V @ rated current then TX_SUP should be >= 3V.

  • AFE4432: Target applications of the AFE4432: How optimized is it?

    Part Number: AFE4432 Hi, I'm looking to use the AFE4432 (or any other similar AFE from the same family) in a project that involves both PPG and a different optical measurement through reflection/absorption in the skin on the near-infrared spectrum …
