6. The specifications are with averaging and in standalone mode only. Performance may degrade depending upon device
use case scenario. When using ADC averaging, refer to the Reference Manual to determine the most appropriate settings
for AVGS.
7. For ADC signals adjacent to V
DD
/V
SS
or XTAL/EXTAL or high frequency switching pins, some degradation in the ADC
performance may be observed.
8. All values guarantee the performance of the ADC for multiple ADC input channel pins. When using ADC to monitor the
internal analog parameters, assume minor degradation.
9. All the parameters in the table are given assuming system clock as the clocking source for ADC.
NOTE
When using high speed interfaces such as the QuadSPI, SAI0,
SAI1 or ENET there may be some ADC degradation on the
adjacent analog input paths. See following table for details.
