MAX9644/MAX9645/MAX9646
Low-Power Comparators with Precision
Reference in 4-Bump UCSP
_______________________________________________________________________________________ 3
Note 1: All devices are 100% production tested at T
A
= +25°C. Temperature limits are guaranteed by design.
Note 2: Too small to be measured in an ATE test environment. Only gross test to catch failures is implemented.
Note 3: Overdrive is defined as the voltage above or below the switching points.
Note 4: Guaranteed by ATE and/or bench characterization over temperature. V
REF
is the average of the trip points.
Note 5: Hysteresis is half the input voltage difference between the two switching points.
Note 6: Includes reference error along with comparator offset voltage error.
