Introduction

Linear-comparators are used to compare two electric signals to determine whether the two compared values are the same or not. These two electric signals could be current or voltage (or their derivatives) and the comparison result is used to trigger certain control operation. MAX967EUA is the industry-leading linear-comparator chip produced by Maxim Integrated. The chip integrates many functions, such as op-amp, noise filter, temperature compensator, and reference voltage selector. In this article, we will introduce the application field and working principle of MAX967EUA.

Application Field

MAX967EUA linear-comparator is suitable for use in the production of high-end systems, including those used in industrial, automotive, and medical systems. In industrial automation, the linear-comparator can be used to compare the measured position or force of a target object with the set point, and then generate a control signal to accurately adjust the operation of the production line. The linear-comparator\'s fast transient response and high-frequency noise immunity make it suitable for any industrial application. In automotive systems, the linear-comparator can serve robots responsible for carrying out automobile assembly, welding, and winding operations. The linear-comparator can detect and compare the signals of the robot positioning system and the components of the control system, thereby constantly adjusting the robot\'s position.In medical systems, the linear-comparator can be used in the manufacture of medical and diagnostic devices, such as blood pressure monitors, blood glucose monitors, and cholesterol monitors. The device can be used to compare measured signals with reference values and convert them into a control signal for device operation.

Working Principle

MAX967EUA linear-comparator consists of three parts: an op-amp, a noise filter, and a temperature compensator. By comparing a reference voltage with the voltage from a signal source, the linear-comparator can determine whether or not the two voltages are equal.The op-amp is used to amplify the signal from the signal source and balance out common-mode voltage and offset voltage. The noise filter is used to reduce electrical interference, which can prevent false values being generated as a result of noise. The temperature compensator is used to normalize temperature fluctuations in order to ensure accurate process comparison.The reference voltage selector is used to select a suitable reference voltage according to the output control range of the linear-comparator. This reference voltage can be adjusted to ensure that the tolerance and hysteresis range of the output control circuit falls within the specified range.

Conclusion

MAX967EUA linear-comparator is an industry-leading product for industrial, automotive, and medical system production. Its wide range of features provides optimal stability and accuracy for the application purpose. MAX967EUA linear-comparator is the ultimate choice for precise applications.
