Quad Voltage Compartor
APPLICATIONS INFORMATION
www.DataSheet4U.com
This quad comparator 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 KΩ should be used. The 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 voltage without damaging the comparator inputs.
Voltages more negative than -300mV should not be used.
