1.3mm x 1.3mm, Low-Power
Dual Comparator
Note 2: All devices are 100% production tested at T
A
= +25NC. Temperature limits are guaranteed by design.
Note 3: Hysteresis is the input voltage difference between the two switching points.
Note 4: V
OS
is the average of the positive and negative trip points minus V
REF
.
Note 5: Overdrive is defined as the voltage above or below the switching points.
