AFE4432: AFE4432

Part Number: AFE4432
Other Parts Discussed in Thread: AFE4403

Tool/software:

Hello,

I would like to adjust AFE4432 configuration to the previously used in AFE4403.

Currently the configuration we're using in AFE4403 is as follow:

This resulting in linear connection to Spo2 (in the ratio of 940 and 660nm LEDs).

When trying to reproduce the results with the same LEDs and PD using the AFE4432, we are receiving polynomial connection. We are trying to configurate the AFE4432 at the same parameters that were used in AFE4403. In terms of internal filtering, dc cancellation. ambient light cancellation - which values we should adjust to be similar to AFE4403?
