3.1 Guard Ring Circuit
The guard ring circuitry can be used to ground any noise from unexpected changes in the electromagnetic field that the capacitative sensor may be exposed to. Two digital guard ring outputs (ADGRDA/ADGRDB) and the associated voltage divider resistors in the circuit are used to drive the guard ring voltage.

What is a Guard Ring and How to Design It Properly
What Is A Guard Ring. A guard ring is often copper trace that is drawn across a node in a circuit. As implied by its name, a guard ring protects the node that it is surrounding from external disturbance. You can find applications of guard ring in PCB design that involves op-amp. The guard ring guards the high impedance input of the op-amp which
What are Guard Rings?
