is recommended to configure PortAD pins as outputs only for low frequency, low load outputs. The impact
on ATD accuracy is load dependent and not specified. The values specified are valid under condition that
no PortAD output drivers switch during conversion.
A.2.2.2
Due to the input pin leakage current as specified in
there will be a voltage drop from the signal source to the ATD input. The maximum source resistance R
specifies results in an error (10-bit resolution) of less than 1/2 LSB (2.5 mV) at the maximum leakage
current. If device or operating conditions are less than worst case or leakage-induced error is acceptable,
larger values of source resistance of up to 10Kohm are allowed.
A.2.2.3
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 1LSB (10-bit resilution), then the external filter capacitor, C

There are two cases to consider.

1. A current is injected into the channel being converted. The channel being stressed has conversion
2. Current is injected into pins in the neighborhood of the channel being converted. A portion of this
