1. Specified by design. Not tested in production.
2. The voltage booster on the ADC switches must be used when VDDA < 2.4 V (embedded I/O switches).
3. Degraded differential linearity error below 10 MHz.
4. Depending on the package,
VREF+ can be internally connected to VDDA and VREF- can be internally connected to VSSA.
5. The tolerance is 4 LSBs for 14-bit resolution, and 2 LSBs for 12-bit, 10-bit and 8-bit resolutions.
