(1) The internal reference current is supplied through the AVCC terminal.
(2) The condition is that the error in a conversion started after tREFON is less than ±0.5 LSB.
(3) The internal reference noise affects ADC performance when the ADC uses the internal reference.
(4) Calculated using the box method: (MAX(–40°C to 105°C) – MIN(–40°C to 105°C)) / MIN(–40°C to 105°C) / (105°C – (–40°C))
