Comparators STMicroelectronics LM139N Overview
The STMicroelectronics LM139N stands out in the market as a high-performance low power quad comparator, crucial for designing efficient and reliable electronics. This product, encapsulated in a 14-pin DIP (Dual In-line Package), integrates four independent precision voltage comparators. These are specifically designed to operate from a single power source while offering the flexibility of dual power operations for complex circuits. The LM139N is recognized for its low power consumption and broad voltage range, making it an indispensable component for applications requiring precise voltage monitoring and decision-making capabilities.
LM139N Features
The LM139N comparator by STMicroelectronics is engineered for versatility and performance. Key features include a wide operating supply voltage range from 2V to 36V and very low supply current drain, which is independent of the magnitude of the supply voltage. This makes the LM139N ideal for battery-powered devices. Additionally, it offers low input biasing current, low input offset voltage and offset current which enhances its accuracy in critical applications. Its ability to operate over a wide temperature range further ensures reliability under varying environmental conditions.
LM139N Applications
- Control Systems: Employed in feedback control mechanisms, the LM139N ensures precise voltage level monitoring which is vital for maintaining system stability.
- Power Supply Management: In power supply circuits, this comparator helps in overvoltage and undervoltage detection, safeguarding against voltage irregularities.
- Battery Chargers: It is used to monitor charge states, enhancing the efficiency and longevity of battery systems.
- Alarm Systems: The LM139N serves as a critical component in alarm circuits by detecting threshold levels which trigger the alarm.
- Automotive Electronics: In automotive applications, it can manage engine sensors and fuel ratios, contributing to optimal vehicle performance.
