APPLICATION INFORMATION
This dual comparator feature high gain, wide bandwidth characteristics. This gives the device oscillation tendencies
if the outputs are capacitive coupled to the inputs via stray capacitance. This oscillation manifests itself during
output transitions (V
OL
to V
OH
). To alleviate this situation input resistors<10kΩ 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 -0.3V should not be used.
