over recommended ranges of supply voltage and operating free-air temperature (unless otherwise noted)

PARAMETER		TEST CONDITIONS	V_CC	MIN	TYP	MAX	UNIT
AV_CC	Analog supply voltage	AVCC and DVCC are connected together, AVSS and DVSS are connected together, V_(AVSS) = V_(DVSS) = 0 V		1.8		3.6	V
V_(Ax)	Analog input voltage range⁽¹⁾	All ADC10_A pins		0		AV_CC	V
I_{ADC10_A}	Operating supply current into AVCC terminal, REF module and reference buffer off	f_ADC10CLK = 5 MHz, ADC10ON = 1, REFON = 0, SHT0 = 0, SHT1 = 0, ADC10DIV = 0, ADC10SREF = 00	2.2 V		68	100	µA
			3 V		78	110
	Operating supply current into AVCC terminal, REF module on, reference buffer on	f_ADC10CLK = 5 MHz, ADC10ON = 1, REFON = 1, SHT0 = 0, SHT1 = 0, ADC10DIV = 0, ADC10SREF = 01	3 V		124	180
	Operating supply current into AVCC terminal, REF module off, reference buffer on	f_ADC10CLK = 5 MHz, ADC10ON = 1, REFON = 0, SHT0 = 0, SHT1 = 0, ADC10DIV = 0, ADC10SREF = 10, VEREF = 2.5 V	3 V		105	160
	Operating supply current into AVCC terminal, REF module off, reference buffer off	f_ADC10CLK = 5 MHz, ADC10ON = 1, REFON = 0, SHT0 = 0, SHT1 = 0, ADC10DIV = 0, ADC10SREF = 11, VEREF = 2.5 V	3 V		72	110
C_I	Input capacitance	Only one terminal Ax can be selected at one time from the pad to the ADC10_A capacitor array including wiring and pad	2.2 V		3.5		pF
R_I	Input MUX ON resistance	AV_CC > 2.0 V, 0 V ≤ V_Ax ≤ AV_CC				36	kΩ
R_I	Input MUX ON resistance	1.8 V < AV_CC < 2.0 V, 0 V ≤ V_Ax ≤ AV_CC				96	kΩ

(1) The analog input voltage range must be within the selected reference voltage range V_R+ to V_R– for valid conversion results. The external reference voltage requires decoupling capacitors. Connect two decoupling capacitors, 10 µF and 100 nF, to VREF to decouple the dynamic current required for an external reference source if it is used for the ADC10_A. Also see the MSP430x5xx and MSP430x6xx Family User's Guide.

Table 5-48 lists the switching characteristics of the ADC.
