Do I need to use a TVS component to between two different ground connections on a printed circuit board (PCB)?
Yes, at the farthest point on the PCB away from a common point connection. At the circuit board level, there is generally some isolation between grounds (analog and digital). At some point of connection within the system, these two grounds are common. At the circuit extremes, a low voltage differential must be maintained in order to prevent ground bounce (GPR), which will affect sensitive IC components.
