Guaranteed by design. 2. The voltage booster on ADC switches must be used for VDDA < 2.4 V (embedded I/O switches). 3. These values are valid for UFBGA169 and one ADC. The values for other packages and multiple ADCs may be different. 4. Direct channels are connected to analog I/Os (PA0_C, PA1_C, PC2_C and PC3_C) to optimize ADC performance. 5. Depending on the package, VREF+ can be internally connected to VDDA and VREF- to VSSA. 6. 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 98.
