Table 40-17. Comparator AC Electrical Specifications
AC CHARACTERISTICS			Standard Operating Conditions: VDD and VDDIO 2.7V to 5.5V (unless otherwise stated) Operating temperature: -40°C ≤ TA ≤ +125°C for Extended Temp
Param. No.	Symbol	Characteristics	Min.	Typ	Max.	Units	Conditions
CMP_1	VIOFF_00	Input Offset Voltage	-33	—	33	mV	COMPCTRLx.HYST = 0x0 COMPCTRLx.SPEED = 0x0
	VIOFF_01		-39	—	39	mV	COMPCTRLx.HYST = 0x1 COMPCTRLx.SPEED = 0x0
	VIOFF_02		-17	—	17	mV	COMPCTRLx.HYST = 0x0 COMPCTRLx.SPEED = 0x3
	VIOFF_03		-19	—	19	mV	COMPCTRLx.HYST = 0x1 COMPCTRLx.SPEED = 0x3
CMP_5	VHYST_00	Input Hysteresis Voltage	25	—	179	mV	COMPCTRLx.HYST = 0x1 COMPCTRLx.SPEED = 0x0
CMP_5	VHYST_01	Input Hysteresis Voltage	43	—	145	mV	COMPCTRLx.HYST = 0x1 COMPCTRLx.SPEED = 0x3
CMP_15	TRESPSS_LS⁽²⁾	Small Signal Response Time, low speed	—	—	234	ns	Comparator reference voltage = AVDD/2 COMPCTRLx.HYST = 0x0 Input overdrive = ± 100 mv COMPCTRL.SPEED = 0x0
CMP_17	TRESPSS_HS⁽²⁾	Small Signal Response Time, high speed	—	—	68	ns	Comparator reference voltage = AVDD/2 COMPCTRLx.HYST = 0x0 Input overdrive = ± 100 mv COMPCTRLx.SPEED = 0x3
CMP_19	COUTVAL_01	Comparator Enabled to Output Valid	—	—	13.6	μs	Comparator module is configured before enabling it COMPCTRLx.SPEED = 0x0
CMP_19	COUTVAL_02	Comparator Enabled to Output Valid	—	—	4	μs	Comparator module is configured before enabling it COMPCTRLx.SPEED = 0x3
Note: Comparator Reference voltage cannot exceed: (VIN(max) - VIOFF(max) - CMP_5(max) - 50mV) ≥ CMP_23 ≥ (VIN(min) + abs(VIOFF(min)) + CMP_5(max) + 50mV). TRESPss_XX is measured from VIN transition to CMPx output toggle. It takes into account only analog propagation delay.
