12-bit ADC characteristics
Unless otherwise specified, the parameters given in Table 45 are derived from tests
performed under the ambient temperature, fPCLK2 frequency and VDDA supply voltage
conditions summarized in Table 9.
Note:
It is recommended to perform a calibration after each power-up.
Table 45.

1.
Based on characterization, not tested in production.
2.
Guaranteed by design, not tested in production.
3.
In devices delivered in VFQFPN and LQFP packages, VREF+ is internally connected to VDDA and VREF- is internally
connected to VSSA. Devices that come in the TFBGA64 package have a VREF+ pin but no VREF- pin (VREF- is internally
connected to VSSA), see Table 5 and Figure 6.
4.
For external triggers, a delay of 1/fPCLK2 must be added to the latency specified in Table 45.
