APPLICATIONS INFORMATION
These dual comparators feature high gain, wide
bandwidth characteristics. This gives the device oscillation
tendencies if the outputs are capacitively coupled to the
inputs via stray capacitance. This oscillation manifests itself
during output transitions (VOL to VOH). To alleviate this
situation, input resistors < 10 k
W should be used.
The addition of positive feedback (< 10 mV) is also
recommended. It is good design practice to ground all
unused pins.
Differential input voltages may be larger than supply
voltage without damaging the comparator’s inputs. Voltages
more negative than −0.3 V should not be used.
