ADC characteristics

Subject to general operating conditions for AVDD, fPCLK2, and TA unless otherwise specified.

Notes:

Unless otherwise specified, typical data are based on TA=25°C and AVDD-AVSS=3.3V. They are given only

as design guidelines and are not tested.

Any added external serial resistor will downgrade the ADC accuracy (especially for resistance greater than

10k

Ω). Data based on characterization results, not tested in production.

Calibration is needed once after each power-up.
