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

Ω 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.
