A.2.3.3 Current Injection
There are two cases to consider.
1. A current is injected into the channel being converted. The channel being stressed has conversion
values of $3FF ($FF in 8-bit mode) for analog inputs greater than VRH and $000 for values less than
VRL unless the current is higher than specified as disruptive condition.
2.
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 VERR =K*RS *
IINJ, with IINJ being the sum of the currents injected into the two pins adjacent to the converted
channel.
