resistance is allowed.
A.2.2.2 Source Capacitance
When sampling an additional internal capacitor is switched to the input. This can cause a voltage drop due
to charge sharing with the external and the pin capacitance. For a maximum sampling error of the input
voltage

A.2.2.3 Current Injection
There are two cases to consider.
1.
A current is injected into the channel being converted. The channel being stressed has conversion

unless the current is higher than specified as disruptive condition.
Current is injected into pins in the neighborhood of the channel being converted. A portion of this
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
