Table 40-33. Channel Conversion Time and ADC Clock
Note:
To achieve optimal performance of the ADC, the analog power supply VDDANA and the ADVREF input voltage must be
decoupled with a 4.7µF capacitor in parallel with a 100 nF capacitor

ADC
TTH (µs)
In case of very high input impedance, this value must be respected in order to guarantee the correct converted value. An
internal input current buffer supplies the current required for the low input impedance (1 mA max)
