3.8 Electrical Characteristics - AC

Some clarifications have been made to the Analog Comparator Specifications table.

Table 35-27. Analog Comparator Specifications


Operating conditions: V_DD = 3.0V T_A = 25ºC
Symbol	Description	Min.	Typ.✝	Max.	Unit	Conditions
V_IN *	Input voltage range	-0.2	—	V_DD	V
I_L	Input leakage current	—	5	—	nA
V_OFF	Input offset voltage	-30	±10	30	mV	0.1V < V_IN < (V_DD - 0.1V)
CMRR *	Common mode input rejection ratio	—	70	—	dB	0.1V < V_IN < (V_DD - 0.1V)
V_HYST	Hysteresis	—	10	—	mV	CTRLA.HYSMODE = `0x1`
		—	20	—		CTRLA.HYSMODE = `0x2`
		—	30	—		CTRLA.HYSMODE = `0x3`
t_RESP *	Response time, rising edge	—	50	—	ns	CTRLA.POWER = `0x0`, V_CM = V_DD/2
t_RESP *	Response time, falling edge	—	150	—	ns	CTRLA.POWER = `0x0`, V_CM = V_DD/2
✝ Unless otherwise specified, data in the “Typ.” column is at T_A = 25°C and V_DD = 3.0V. These parameters are not tested and are for design guidance only. * These parameters are characterized but not tested in production.
