Linear Comparators

LM339DR Description

The LM339DR from Texas Instruments is a quad differential comparator designed for general-purpose applications. Packaged in a 14-SOIC surface-mount form factor, this IC is optimized for low power consumption, with a quiescent current of 2.5mA (max) and an input bias current as low as 0.25µA. It operates over a wide supply voltage range (2V–30V single or ±1V–15V dual), making it versatile for various analog and digital systems. The device features low input offset voltage (5mV max @ 30V) and an open-drain output capable of sinking 20mA, enabling direct interfacing with logic circuits.

LM339DR Features

• Quad Comparator Design: Four independent comparators in a single package, reducing board space and cost.
• Wide Voltage Range: Supports single (2V–30V) or dual (±1V–15V) supplies for flexible power configurations.
• Low Power Consumption: Quiescent current ≤2.5mA, ideal for battery-operated devices.
• High Output Drive: 20mA sink current for robust signal conditioning.
• Low Input Bias Current: 0.25µA (max) minimizes loading effects on signal sources.
• Robust Packaging: 14-SOIC (Tape & Reel) with MSL1 (Unlimited) moisture sensitivity, ensuring reliability in automated assembly.
• RoHS3 & REACH Compliant: Environmentally friendly and suitable for global markets.

LM339DR Applications

• Voltage Monitoring: Over/under-voltage detection in power supplies and battery management.
• Signal Conditioning: Window comparators, zero-crossing detectors, and pulse-width modulation.
• Industrial Control: Threshold detection in sensors, motor control, and automation systems.
• Consumer Electronics: Level shifting, logic interfacing, and audio processing.
• Automotive Systems: Fault detection and signal integrity checks in harsh environments.

Conclusion of LM339DR

The LM339DR excels in precision, efficiency, and versatility, making it a preferred choice for analog signal comparison across industries. Its low power consumption, wide voltage range, and robust output drive distinguish it from similar comparators, while its quad-channel integration optimizes PCB space. Whether in industrial, automotive, or consumer applications, this IC delivers reliable performance under varying conditions, backed by Texas Instruments' quality assurance.
