Header Function
When a shunt is present across its pins, each header DC couples its respec-
tive input connector to the associated input of the CS3318.
When no shunt is present across the header’s pins, its respective input con-
nector will be AC coupled to the associated input of the CS3318.
When a shunt is present across its pins, each header DC couples its respec-
tive output connector to the associated output of the CS3318.
