Part Number: AFE4490SPO2EVM

Hello Guys,

Good day.

Is it possible to run multiple AFE4490SPO2EVM in one GUI?

Thanks!

    Hello Art,

    No, the AFE4490 GUI does not support multiple boards.

    Thanks Praveen!

    Some follow-up questions from our customer:

    1) Is it possible to install a virtual machine to run 2 AFE4490SPO2EVMs at the same time?. Or he needs 3 PC's for 3 EVMs?

    2) He have a separation between the photodiode and led of 5 mm. Rf=10k, ILED=30 mA and the second stage is disable. He gets a curve which goes in the negative area (maybe half of the amplitude) . Is this caused by the dark current or the ambient light?

    Thanks!

    Art,

    1. The GUI can only be instantiated once on a PC to connect to an EVM. So he will need 3 PCs.
    2. Without knowing much details about the mechanical arrangement of the sensors and the effect of ambient light / dark current etc., it is difficult to guess the reason for the negative data.Please share additional details like the test setup and the data waveforms.
