This table lists the performance characteristics of the digital-to-analogue converter over the full range
of process variation, operating temperature and supply voltage.

Voltage Reference
This table lists the performance characteristics of the internal voltage reference over the full range of
process variation, operating temperature and supply voltage.

Applications which use the analogue inputs or outputs with the internal reference voltage must have
external decoupling capacitors connected to the Vref pin. The recommended decoupling on this pin is
a 100nF ceramic capacitor in parallel with a 4.7µF tantalum or aluminium electrolytic capacitor.
