Hello Holger, This seems to be a mistake in the MSP430G22x0 datasheet as there is indeed no VEREF+ pin on the MSP430G2230 , I will ask the documentation team for confirmation. Otherwise the ADC input voltage can exceed the internal voltage reference of 2.5 V without damaging the IC (readings will clip at 1023) so long as the voltage in question does not exceed the power supply voltage at DVCC. Regards, Ryan
