LM339 Quad Comparator Integrated Circuit – DIP Package

The LM339 is a low-power quad voltage comparator IC. It contains four independent voltage comparators that can operate from a single power supply over a wide voltage range. The device is designed for precision and low power consumption, suitable for a variety of analog signal processing tasks.

🔧 Key Features

• 4 independent voltage comparators in one package
• Wide supply voltage range: 2V to 36V (single supply) or ±1V to ±18V (dual supply)
• Low supply current, independent of supply voltage
• Open-collector output for wired-AND capability
• Response time: typically 300 ns
• Low input offset voltage
• Standard DIP package for easy prototyping

🧰 Applications

• Zero-crossing detectors
• Voltage level detectors
• Window comparators
• Analog-to-digital converters
• Pulse width modulation circuits
• Oscillators and timers

📦 Package Includes
