Hello,

This question was answered in the previous thread here: https://e2e.ti.com/support/interface/f/138/t/818285

The ADCs are not exposed to the external pins, and the amplifiers that sit between the pins and the ADC have a very high input impedance. The input bias current should be no more than 5nA. The ADCs do not source current.

Regards,
