The output impedance of the analog source must be low enough to assure full loading
of the sample capacitance (

of the sample time
The differential impedance r D of the analog reference voltage source must be less than
1 k at reference supply voltage.
Exceeding these limit values at one or more input channels will cause additional
current which is sinked / sourced at these channels. This may also affect the accuracy
of other channels which are operated within these specifications.
