each of the plurality of switch assemblies includes:
a first switch coupled between a respective input of the plurality of inputs and an internal node;
a second switch coupled to the internal node; and
a third switch directly coupled to the internal node;
the input of the buffer is coupled to the respective second switches of the first, second, and third switch assemblies;
and
the output of the buffer is coupled to the respective third switches of the second and third switch assemblies instead of the first switch assembly.
