Introduction

The LMV393M is a popular CMOS Comparator from Texas Instruments. It is a dual channel comparator which includes two independent, high-speed voltage comparators, each with its own dedicated output. The device operates from a single supply voltage of 5V, and it can accept an input voltage ranging from -0.3V to VCC+0.3V. Both channels feature an extremely low propagation delay, ensuring that they are able to accurately compare input signals in the shortest time possible. Additionally, the comparator is designed to have a low supply current, a wide common-mode range and low input offset voltage.

Application Field

The LMV393M is a popular choice for many different applications due to its robust design and high-performance capabilities. It is commonly used in a variety of automotive, industrial, and consumer applications such as time-delay relays, temperature sensing and alarm systems, data acquisition systems, and frequency discriminators. The LMV393M is also used in digital logic applications and circuit protection devices, as it can compare input signals and accurately identify over-voltage and under-voltage conditions. In addition, the comparator is ideal for use in power-supply regulation and control circuits, as it can quickly identify fluctuations in voltage.

Working Principle

The LMV393M is a rail-to-rail or split supply operation comparator that is designed to work in both inverting and non-inverting operation. When the LMV393M is operating in non-inverting mode, it will compare the two voltages presented to the two inputs and output either a "low" or "high" signal. In non-inverting mode, the output will be "high" when the voltage at the non-inverting input is greater than the voltage at the inverting input. Conversely, the output will be "low" when the voltage at the non-inverting input is less than the voltage at the inverting input. Similarly, the LMV393M can operate in inverting mode and it will output either a "low" or "high" signal, depending on the comparison of the voltage at the inverting and non-inverting inputs.

The LMV393M also features a push-pull output stage that makes it much easier to drive multiple gates and logic devices. Moreover, the comparator features low supply current, which is important in applications that are powered by small batteries or are subject to power supply noise. Additionally, the device features low offset voltage, ensuring that it can accurately compare input signal levels even when the signals are close in voltage levels.

Conclusion

The LMV393M is a popular CMOS Comparator from Texas Instruments that is used in a wide variety of applications. It features two independent, high-speed voltage comparators, and it canaccept an input voltage ranging from -0.3V to VCC+0.3V. Additionally, the comparator is designed to have a low supply current, a wide common-mode range and low input offset voltage. The LMV393M can operate in both inverting and non-inverting mode, and it has a push-pull output stage that makes it easier to drive logic devices. Overall, the LMV393M is an excellent choice for applications that require accurate and high-speed voltage comparisons.
