Notes:

1. Unless otherwise specified, typical data are based on TA=25°C and VDD-VSS=5V. They are given only as design guide-

lines and are not tested.

2. When VDDA and VSSA pins are not available on the pinout, the ADC refers to VDD and VSS.

3. Any added external serial resistor will downgrade the ADC accuracy (especially for resistance greater than 10kΩ). Data

based on characterization results, not tested in production.

4. The stabilization time of the AD converter is masked by the fi

rst tLOAD. The first conversion after the enable is then always valid.
