• Description: Low Power Low Offset Voltage Comparators
• Manufacturer: TSC [Taiwan Semiconductor Company, Ltd]

Application information
This 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
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.
