12-bit ADC characteristics
Unless otherwise specified, the parameters given in Table 41 are derived from tests
performed under the ambient temperature, fPCLK2 frequency and VDDA supply voltage
conditions summarized in Table 8.
Note:
It is recommended to perform a calibration after each power-up.

1.
Based on characterization results, not tested in production.
2.
Guaranteed by design, not tested in production.
3.
VREF+ can be internally connected to VDDA and VREF- can be internally connected to VSSA, depending on the package.
Refer to Section 3: Pinouts and pin description for further details.
4.
For external triggers, a delay of 1/fPCLK2 must be added to the latency specified in Table 41.
