LM339N General Description

The LM339N is a quad comparator IC (integrated circuit) manufactured by various semiconductor companies. It consists of four independent voltage comparators designed for use in analog applications that require accurate comparisons between two voltage levels. Each comparator in the LM339N has a differential input stage and a single output stage, making it capable of comparing voltages and driving logic circuits directly.The LM339N operates from a single power supply voltage ranging from 2V to 36V and can work with dual supplies as well. It features low input offset voltage, low input bias current, and high input impedance, making it suitable for precision applications. The output stage can sink or source up to 16mA, allowing it to directly drive TTL or CMOS logic levels.The IC is housed in a standard DIP (Dual In-line Package) or SOIC (Small Outline Integrated Circuit) package, making it easy to integrate into various electronic circuits. With its versatile features and wide supply voltage range, the LM339N finds applications in voltage monitoring circuits, voltage level detection, window comparators, and voltage regulators, among others
