33.7.5 Analog Comparator Characteristics

Table 33-20. Electrical and Timing (Device Variant A)
Symbol	Parameter	Conditions	Min.	Typ.	Max.	Units
	Positive input voltage range		0	-	V_DDANA	V
	Negative input voltage range		0	-	V_DDANA	V
	Offset	Hysteresis = 0, Fast mode	-15	0.0	+15	mV
	Offset	Hysteresis = 0, Low power mode	-25	0.0	+25	mV
	Hysteresis	Hysteresis = 1, Fast mode	20	50	80	mV
	Hysteresis	Hysteresis = 1, Low power mode	15	40	75	mV
	Propagation delay	Changes for V_ACM=V_DDANA/2  100mV overdrive, Fast mode	-	60	116	ns
	Propagation delay	Changes for V_ACM=V_DDANA/2  100mV overdrive, Low power mode	-	225	370	ns
t_STARTUP	Startup time	Enable to ready delay Fast mode	-	1	2	μs
t_STARTUP	Startup time	Enable to ready delay Low power mode	-	12	19	μs
V_SCALE	INL ⁽³⁾		-1.4	0.75	+1.4	LSB
	DNL⁽³⁾		-0.9	0.25	+0.9	LSB
	Offset Error ^(1,2)		-0.200	0.260	+0.920	LSB
	Gain Error ^(1,2)		-0.89	0.215	0.89	LSB

Note:

According to the standard equation V(X) = V_LSB * (X + 1); V_LSB = V_DDANA / 64.
Data computed with the Best Fit method.
Data computed using histogram.
