TS2903 Datasheet, PDF (4/6 Pages) Taiwan Semiconductor Company, Ltd – Dual Voltage Comparator

Applications 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.
