Param. No.	Symbol	Characteristics	Min.	Typ.	Max.	Units	Conditions
CMP_5	VHYST	Input Hysteresis Voltage	10	—	84	mV	COMPCTRLn.HYSTEN = 0x1 COMPCTRLn.HYST = 0x0
			22	—	120		COMPCTRLn.HYSTEN = 0x1 COMPCTRLn.HYST = 0x1
			37	—	142		COMPCTRLn.HYSTEN = 0x1 COMPCTRLn.HYST = 0x2
			49	—	164		COMPCTRLn.HYSTEN = 0x1 COMPCTRLn.HYST = 0x3
CMP_15	TRESP_SS⁽³⁾	Small Signal Response Time	—	—	13.8	µs	Comparator ref voltage = AVDD/2, COMPCTRLn.HYSTEN = 0x0, COMPCTRLn.SPEED = 0x0, Input overdrive = ± 100mV
				—	2.9		Comparator ref voltage = AVDD/2, COMPCTRLn.HYSTEN = 0x0, COMPCTRLn.SPEED = 0x1, Input overdrive = ± 100mV
				—	1.6		Comparator ref voltage = AVDD/2, COMPCTRLn.HYSTEN = 0x0, COMPCTRLn.SPEED = 0x2, Input overdrive = ± 100mV
				—	0.84		Comparator ref voltage = AVDD/2, COMPCTRLn.HYSTEN = 0x0, COMPCTRLn.SPEED = 0x3, Input overdrive = ± 100mV
CMP_19	COUTVAL	Comparator Enabled to Output Valid	—	—	81	µs	COMPCTRLn.SPEED = 0x0
				—	4.7		COMPCTRLn.SPEED = 0x1
				—	3.2		COMPCTRLn.SPEED = 0x2
				—	2.7		COMPCTRLn.SPEED = 0x3
Note: Typical values at 25°C only. Comparator Ref voltage cannot exceed (VIN(max) - VIOFF(max) - CMP_5(max) - 50 mV) ≥ C_VREFRNG ≥ (VIN(min) + abs(VIOFF(min)) + (CMP_5(max) + 50 mV)) . TRESP_SS_XX is measured from VIN transition to CMPx output toggle. It takes into account only analog propagation delay.
