AFE4950: Max sample rate for 6 LED PPG

Part Number: AFE4950
Other Parts Discussed in Thread: AFE4490

Hi,

I would like to use AF4490 for acquiring PPG signals with 6 LEDs.

Can someone confirm if I can get 1000 SPS with 6 LEDs?

Regards,
Anurag

Hello Anurag,

I'm confused, why do you quote both the AFE4950 and AFE4490? Are you using both AFEs?

In any case, the sample rate of the AFEs does not depend on the number of LEDs.

Kind regards,
Nick Z

Hi Nick,

Sorry for the typo, I am focusing on AFE4950.
I want to capture 6000+ SPS.
Will it be possible to achieve this throughput with above AFE?

Regards,

Anurag

Hello Anurag,

Since this is an NDA restricted device, we'll need to follow up offline. I just sent you a message with all the details you need.

Kind regards,
Nick Z.
