31.10 Internal Voltage Reference Specifications

Table 31-12. Internal Voltage Reference DC Electrical Specifications
DC CHARACTERISTICS			Standard Operating Conditions: VDDIO = AVDD = VDD 1.62V to 3.63V (unless otherwise stated) Operating Temperature: -40°C ≤ TA ≤ +85°C for Industrial
Param. No.	Symbol	Characteristics	Min.	Typ.	Max.	Units	Conditions
VR_1	IREF⁽¹⁾	Internal Voltage Reference ADC.REFCTRL.REFSEL = INT1V DAC.CTRLB.REFSEL = INT1V	0.98	1	1.02	V	Over full operating temperature range
VR_3	IREF⁽¹⁾		0.99	1	1.01	V	25 °C
VR_9a	ACIREF⁽²⁾	Internal Voltage Reference Comparator AC.COMPCTRLn.MUXNEG = Bandgap	1.08	1.1	1.12	V	Over full operating temperature range
VR_9b	ACIREF⁽²⁾	Internal Voltage Reference Comparator AC.COMPCTRLn.MUXNEG = Bandgap	1.09	1.1	1.11	V	25 °C
Note: ADC and DAC reference voltages < 2.4V (i.e., < 500µV/step) is not practical and peripheral performance is not guaranteed. See parameter CMP_23 for Comparator Reference voltage range information.
