2. Current is injected into pins in the neighborhood of the channel being converted. A portion of this
= V
current is picked up by the channel (coupling ratio K), This additional current impacts the accuracy
of the conversion depending on the source resistance.
The additional input voltage error on the converted channel can be calculated as
V
to the converted channel.
