I'm working with an AD7983 and hoping to get more information regarding the internal functionality of the REF pin. The datasheet describes how to use this pin from a top-level perspective, but I'm looking for a more technical description.
How does it interface with the internals of the ADC? Is there an example schematic to better describe this?
What are the effects on the internal circuitry as the reference voltage increases/decreases?
Does the pin have any protection from transients?
