LM393 – Comparator Module

The LM393 is a low-power, low-offset voltage dual comparator designed for precision voltage sensing applications. It operates with a wide voltage range from 2V to 36V (single supply) or ±1V to ±18V (dual supply), making it versatile for various circuit designs. The device features low input offset voltage, low power consumption, and open-collector outputs, allowing direct interfacing with logic circuits. The DIP-8 package makes it easy to integrate into through-hole PCB designs. Common applications include voltage level detection, zero-crossing detection, and signal conditioning in power management and industrial control systems.
