Low Power Low Offset Quad Comparators

4/7

Version: A09

Application Description

This quad 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 (VOL to VOH). 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.
