AFE4900: Information and AFE4490 comparison

Hi,

I am considering testing the AFE4900 for PPG vital signs monitoring, so far I have worked with the AFE4490 and the registers stage1, stage2 and LED control are very useful for our application.

I couldn't find much information about the AFE4900, are the LED control possibilities similar to the AFE4490 - will the transition from AFE4490 should be easy?

Does the AFE4900 EVM allow control over the different LED currents, TIA gains, etc?

Is it possible to use our own software with the AFE4900 EVM?

Thanks,
Tomer
