AFE4403: PPG INVERTED WAVEFORM

Part Number: AFE4403

Hello All,

Iam planning to use AFE4403 for SPO2 & Heart Rate Monitoring system. I've gone through reference design documents and also I've read other posts in the forum where the AFE4403 output looks inverted from a typical PPG Signal. I've read that that output of AFE44023 is WITHOUT any inversion.

But I cannot display an inverted waveform on the patient monitor. How to display the correct waveform ? Should I just reverse the digital output of the AFE4403 so that the waveform looks normal?
