APPLICATIONS INFORMATION

These quad 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

addition of positive feedback (< 10 mV) is also

recommended. It is good design practice to ground all

unused input pins.

Differential input voltages may be larger than supply

voltages without damaging the comparator’s inputs.

Voltages more negative than –300 mV should not be used.

during output transitions (V

to V ). To alleviate this

situation input resistors < 10 kΩ should be used. The
