LMV7235M5 Integrated Circuits (ICs)

Introduction

The LMV7235M5 is a high performance, single comparator designed specifically for use in industrial, telecommunications and instrumentation applications. It is a high-speed, high voltage, low power consumption comparator and offers a wide range of output configurations for complex conditioning and system monitoring. The LMV7235M5 is ideal for applications in which both speed and power consumption are important and advanced features such as voltage gain and hysteresis are desirable.

Application Field

The LMV7235M5 is used for applications in industrial, telecommunications and instrumentation systems. It can be used to perform threshold detection, limit sensing, switching, synchronization, timing and logic functions. Some of the typical applications of the LMV7235M5 include level detection, temperature monitoring, position/velocity sensing, pulse/frequency processing, and open/closed loop control.

Working Principle

The LMV7235M5 consists of two pins: an input pin (Vin) and an output pin (Vout). When the input voltage is lower than the reference voltage, the output voltage remains low. When the input voltage is higher than the reference voltage, the output voltage is high. The LMV7235M5 features a true open-drain output, enabling it to be driven in open-drain "push-pull" mode as well as standard open collector mode. It also has an internal resistor to pull up its output voltage in case a pull-up resistor is not connected externally.

The LMV7235M5 also has an integrated Schmitt trigger input stage for noise control and an integrated EMI filter for improved EMI immunity and performance. The device is capable of sourcing and sinking currents of up to 10mA at voltages from 4.5V to 28V. The device also offers an adjustable voltage gain, adjustable hysteresis, and an output enable function.

Conclusion

The LMV7235M5 is a high performance, single comparator designed to meet the needs of industrial, telecommunications and instrumentation applications. It offers a wide range of output configurations, and features improved noise control, EMI immunity and performance through its integrated Schmitt trigger input stage and EMI filter. It is capable of sourcing and sinking currents of up to 10mA, with adjustable voltage gain and hysteresis, as well as an output enable function.
