Working Principle of the LMV339MX

The LMV339MX Linear-Comparators feature a new, low-power amplifier with a single input stage and a rail-to-rail output stage. It has a fast response time, an ultra low input offset voltage, and no pullup resistor is required. This Linear–Comparator can operate from a single 5 V supply and is CMOS compatible. The input stage utilizes a new differential output amplifier to reduce offset voltage and provide higher precision and speed. The output stage drives a low impedance load and provides rail-to-rail voltage swings.

The LMV339MX Linear–Comparator compares the input voltage differential to a reference voltage. It then outputs a digital signal that changes when the input voltage differentialexceeds the reference voltage. The output signal is logic high when the input voltage isNegative and logic low when the input voltage differential is Positive.

Conclusion

The LMV339MX Linear-Comparator is an ideal device for high-speed, CMOS voltage comparison applications. It is designed with a single input stage, a rail-to-rail output stage and a low power amplifier for ultra low input offset voltage. It offers a wide range of application fields and its performance is excellent. The LMV339MX Linear-Comparator can also be used for fan controls, motion detectors, industrial controls, ground fault sensing, and voltage level detection.
