1. Guaranteed by design, not tested in production.
2. The pull-up is designed with a true resistance in series with a switchable PMOS. This PMOS contribution to the series
resistance is minimal (~10% order).

12-bit ADC characteristics
Unless otherwise specified, the parameters given in Table 49 are derived from tests
performed under the conditions summarized in Table 18: General operating conditions.
It is recommended to perform a calibration after each power-up.
