12-bit ADC characteristics
Unless otherwise specified, the parameters given in Table 43 are derived from tests
performed under ambient temperature, fPCLK2 frequency and VDDA supply voltage
conditions summarized in Table 7.
Note:
It is recommended to perform a calibration after each power-up.

1.
VREF+ can be internally connected to VDDA and VREF- can be internally connected to VSSA, depending on the package.
Refer to Section 3: Pin descriptions for further details.
2.
For internal triggers, a delay of 1/fPCLK2 must be added to the latency specified in Table 43.
