Comparators STMicroelectronics LM239N Overview
The LM239N from STMicroelectronics is a versatile low-power quad comparator, designed for applications requiring multiple voltage comparisons without compromising on power efficiency. This IC is housed in a 14-pin DIP package, providing a robust solution for a variety of challenging environments. The LM239N stands out for its ability to operate from a single power supply over a wide range of voltages or from dual supplies for increased flexibility. This feature makes the LM239N an ideal choice for industrial, automotive, and consumer applications where reliability and cost-effectiveness are crucial. The incorporation of four independent comparators in a single package not only reduces space requirements but also minimizes power consumption, making it an excellent option for design engineers looking to optimize their systems.
LM239N Features
The LM239N offers several distinctive features that enhance its applicability in diverse electronic circuits:
- Wide single supply voltage range or dual supplies for all devices: 2V to 36V or ±1V to ±18V.
- Very low supply current drain independent of supply voltage: 0.8 mA typical.
- Low input biasing current: 25 nA typical.
- Low input offset current: ±5 nA and input offset voltage: ±3 mV.
- Input common-mode voltage range includes ground.
- Differential input voltage range equal to the power supply voltage.
- Output can drive loads up to 50 mA.
- Low output saturation voltage.
LM239N Applications
- Control Systems: Used for precise control loops, enabling accurate measurement and control of system parameters.
- Voltage Monitoring: Essential for detecting voltage levels to prevent overvoltage conditions in power-sensitive circuits.
- Multi-Vibrator Circuits: Acts as a critical component in generating oscillating signals.
- Window Comparators: Suitable for applications requiring a specific voltage window for operational safety and functionality.
- Limit Comparators: Helps in setting operational limits in various electronic devices, ensuring device safety and functionality within specified boundaries.
- Level Shifters: Utilized to interface between different logic levels, bridging components that operate at various voltages.
- Peak Detectors: Critical in capturing the peak value of a signal, useful in signal processing applications.
