Contribution only due to the reference and buffer including package. This does not include resistance due to PCB trace, etc.
(5)
Two decoupling capacitors, 10F and 100nF, should be connected to VREF to decouple the dynamic current required for an external
reference source if it is used for the ADC12_A. See also the MSP430x5xx Family User's Guide (SLAU208).
(6)
Calculated using the box method: (MAX(-40 to 85°C) – MIN(-40 to 85°C)) / MIN(-40 to 85°C)/(85°C – (–40°C)).
(7)
The condition is that the error in a conversion started after tREFON is less than ±0.5 LSB. The settling time depends on the external
capacitive load when REFOUT = 1.
