The LM339N/NOPB is a high-performance quad differential comparator manufactured by Texas Instruments, designed to provide precise voltage comparisons, tailored for applications requiring multiple voltage level detections. This device is a common choice for industrial, automotive, and consumer electronics due to its versatility and reliability.

Key Features

• Quad Comparators: The device contains four independent voltage comparators that operate from a single power supply over a wide range of voltages.
• Wide Voltage Range: The LM339N/NOPB operates from a single power supply over a wide range of voltages or can operate from dual supplies if needed.
• Low Supply Current Drain: It is designed for low power consumption, drawing minimal current, which is ideal for battery-powered applications.
• Open Collector Outputs: The outputs are open collector, which means they can be connected to achieve wired-AND relationships.
• Input Offset Voltage: Specifications as low as 2 mV make this device suitable for precision applications.
• Common-Mode Input Voltage Range: Includes ground, which enhances the flexibility of the device in single-supply applications.
• Differential Input Voltage Range: Equal to the supply voltage range.
• Low Input Bias Current: This makes the device suitable for high-impedance sensor interfaces and battery monitoring.

Applications

The LM339N/NOPB is widely used in various applications due to its flexibility and performance. Some common applications include:

• Limit Comparators
• Simple Analog to Digital Converters (ADCs)
• Voltage Monitoring
• Battery Chargers
• Window Comparators
• Waveform Generators
• Motor Control
• Logic Voltage Translators

Environmental and Quality

The "NOPB" designation indicates that the product is part of Texas Instruments' green initiative, standing for "No Lead (Pb)", which means it is RoHS compliant and free from lead, making it suitable for eco-friendly applications and markets with strict lead-free requirements.

Package and Availability

The LM339N/NOPB is available in a 14-pin PDIP (Plastic Dual-In-Line Package) which is suitable for through-hole mounting, providing ease of integration into a wide range of electronic circuits. It is widely available and supported by Texas Instruments' comprehensive technical documentation.
