(1)

The actual current consumption of this mode fluctuates during operation over a 1-s period. The value shown is an average using the

default data flash configuration.

(2)

The actual current consumption of this mode fluctuates during operation over a user-configurable period. The value shown is an average

using the default data flash configuration.

Effective input resistance(4)

(1)

Full-scale reference

(2)

Post-calibration performance and no I/O changes during conversion with VSS as the ground reference

(3)

Uncalibrated performance. This gain error can be eliminated with external calibration.

(4)

The A/D input is a switched-capacitor input. Since the input is switched, the effective input resistance is a measure of the average

resistance.
