LM339 Bridgold Quad Comparator 10pcs DIP14 Wide Input Low Power

Description

Product Overview

Designed for demanding industrial and scientific applications, the LM339 Bridgold quad differential comparator delivers reliable performance across a broad range of voltage levels. Each of the four independent comparators shares a common-mode input range that extends from ground up to VCC-1.5 V, allowing designers to interface directly with high-voltage digital logic without additional level-shifting circuitry. The device features a low input offset voltage of ±2 mV, ensuring precise threshold detection even in noisy environments.

Beyond its electrical characteristics, the LM339 is packaged in a convenient 14‑pin DIP format that simplifies both breadboard prototyping and automated surface‑mount assembly. The compact footprint occupies minimal board space while providing robust pin spacing for reliable solder joints. Thermal performance is well‑managed, with the component capable of dissipating heat efficiently under continuous operation, making it suitable for both low‑power and power‑intensive designs.</n

Reliability is a cornerstone of the LM339’s design. Bridgold subjects each production batch to rigorous testing for offset voltage, supply current, and output compatibility, guaranteeing consistent behavior across all units. The comparator’s open‑collector outputs are TTL‑compatible, yet they can be pulled up to higher voltages to accommodate MOS, CMOS, and DTL logic families, offering flexibility for mixed‑signal system architects.

The 10‑piece kit provides ample spares for development, testing, and production runs, reducing lead times and inventory costs for engineers and procurement teams alike. With a price point of $7.99 for the entire set, the LM339 delivers exceptional value, making it a practical choice for hobbyists, educational institutions, and professional engineers seeking high‑performance differential comparison in a compact, cost‑effective package.

Usage

In industrial automation, the LM339 excels at monitoring voltage thresholds for motor‑control circuits, providing rapid response to over‑current conditions and safeguarding equipment from damage. Its fast switching capability ensures that protective actions are taken within microseconds, preserving both machinery and operator safety.

Sensor interfacing applications benefit from the comparator’s wide input range and low offset, enabling accurate detection of small signal variations from temperature, pressure, or light sensors. Engineers can design compact front‑end modules that translate analog sensor outputs into clean digital signals for downstream processing.

Battery‑powered devices, such as remote telemetry units and portable instrumentation, profit from the LM339’s low quiescent current of 1.3 mA per comparator. This minimal power draw extends operational life while still delivering reliable voltage comparison for charge‑control logic and power‑management algorithms.

Educational laboratories and hobbyist projects often require versatile components that are easy to integrate. The DIP14 package of the LM339 allows students to experiment with comparator circuits on standard breadboards, fostering hands‑on learning of analog‑digital interfacing without the need for specialized tooling.
