AFE4410: Current Draw on TX_SUP

Sam Nelson
Prodigy 10 points
Part Number: AFE4410

I am seeing abnormally high current draw on the TX_SUP rail while in idle mode i.e. not driving LEDs. Across 10 samples I am seeing between 5 and 40 uA. A larger test set shows much wider variation, anywhere from 1-200 uA while idle at this rail. Please help me understand if this is expected, or if there are areas I should troubleshoot.
