1 Single Supply Quad Comparator JN. 21 Product Description The consists of four independent precision voltage comparators. These were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. These comparators also have a unique characteristic in that the input common-mode voltage range includes ground, even though operated from a single power supply voltage. Features Wide supply ltage range: 2.V to 32V. Low supply current drain independent of supply voltage. Low input biasing current: 25 n typ. Low input offset current: 5 n typ. Low input offset voltage: 2 mv typ. Input common-mode voltage range includes GND. Differential input voltage range equal to the power supply voltage Low output saturation voltage. Output voltage compatible with TTL, MOS and CMOS logic. pplications pplication areas include limit comparators, simple analog to digital converters; pulse, square wave and time delay generators; wide range VCO; multivibrators and high voltage digital logic gates.

5 Typical pplications (V CC =5V) These quad comparators feature high gain, wide bandwidth characteristic. 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 (V OL to V OH ). To alleviate this situation, input resistors< Ω should be used. The addition of positive feedback (<1mV) 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 input. ltage is more negative than -.3V should not be used.
