1. Guaranteed by design.

2. Depending on the package, VREF+ can be internally connected to VDDA and VREF- to VSSA.

3. These values are valid UFBGA176+25 and one ADC. The values for other packages and multiple ADCs might be different

4. The voltage booster on ADC switches must be used for VDDA < 2.4 V (embedded I/O switches).

5. The tolerance is 10 LSBs for 16-bit resolution, 4 LSBs for 14-bit resolution, and 2 LSBs for 12-bit, 10-bit and 8-bit resolutions.

Table 94. Minimum sampling time vs RAIN

Data valid up to 130 °C, with a 47 pF PCB capacitor and VDDA=1.6 V.
