(1) Internal reference noise affects ADC performance when ADC uses internal reference. See Designing With the MSP430FR58xx, FR59xx, FR68xx, and FR69xx ADC for details on optimizing ADC performance for your application with the choice of internal or external reference.

(2) Buffer offset affects ADC gain error and thus total unadjusted error.

(3) Buffer offset affects ADC gain error and thus total unadjusted error.

(4) The internal reference current is supplied through the AVCC terminal.

(5) Calculated using the box method: (MAX(–40°C to 85°C) – MIN(–40°C to 85°C)) / MIN(–40°C to 85°C)/(85°C – (–40°C)).

(6) The condition is that the error in a conversion started after t_REFON is less than ±0.5 LSB.
