Texas Instruments LM339AN Quad Comparator DIP 14 Pins

The Texas Instruments LM339AN/NOPB is a precision quad voltage comparator designed for applications requiring low power consumption and high accuracy. Each device contains four independent comparators with a maximum offset voltage specification of 2mV, ensuring reliable performance in a wide range of electronic circuits.

This comparator operates from a single power supply over a broad voltage range of 2V to 36V, and can also be used with split power supplies. The low supply current drain of 0.8mA is independent of the supply voltage, making it ideal for battery-powered systems. With a fast response time of 1.3µs, it is suitable for high-speed signal processing.

Key Features

• Low input biasing current: 25nA
• Low input offset current: ±5nA
• Offset voltage: ±3mV
• Input common-mode voltage range includes GND
• Differential input voltage range equals the power supply voltage
• Low output saturation voltage: 250mV at 4mA
• Output voltage compatible with TTL, DTL, ECL, MOS, and CMOS logic systems

The DIP-14 package ensures easy through-hole mounting, ideal for prototyping and production. Operating temperature range is from 0°C to 70°C, making it suitable for most commercial applications. This comparator is a cost-effective solution for precision voltage comparison, signal conditioning, and level detection in a wide variety of electronic designs.
