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 conditions.
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.
A.2.4 ATD accuracy (5V Range)
Table A-11 specifies the ATD conversion performance excluding any errors due to current injection,
input capacitance and source resistance.
