The LM393 is a dual voltage comparator integrated circuit (IC) commonly used in a variety of electronic circuits. Developed by Texas Instruments, it offers two independent precision voltage comparators with an open-collector output stage. The LM393 is designed to operate from a single power supply over a wide range of voltages, making it versatile for various applications.

With its low input offset voltage and offset current, the LM393 ensures precise comparisons of voltage levels. Its wide range of operating temperature (-40°C to 125°C) and high input impedance make it suitable for use in diverse environments and circuit configurations.

Typical applications of the LM393 include voltage level detection, pulse width modulation, line-following robots, motor speed control, and overvoltage protection circuits. Its popularity stems from its simplicity, reliability, and affordability, making it a staple component in many electronic projects and systems. Whether in industrial control
systems or hobbyist electronics, the LM393 continues to serve as a fundamental building block for voltage comparison tasks.
