Linear Comparators

LM393NG Description

The LM393NG is a general-purpose comparator from onsemi, designed for a wide range of applications in the electronics industry. This 2-element, through-hole mounted comparator is housed in an 8-pin DIP package and operates over a temperature range of 0°C to 70°C. With a typical output current of 16mA at 5V and an input offset voltage of up to 5mV at 30V, the LM393NG offers reliable performance in various applications.

LM393NG Features

• Voltage Supply Range: The LM393NG can operate with a single supply voltage ranging from 2V to 36V or dual supplies ranging from ±1V to ±18V, providing flexibility in power supply options.
• Low Input Bias Current: The maximum input bias current is 0.25µA at 5V, ensuring minimal loading on the input signal source.
• Low Quiescent Current: The maximum quiescent current is 2.5mA, contributing to low power consumption in applications where power efficiency is critical.
• Moisture Sensitivity Level (MSL): Rated at MSL 1, the LM393NG can be stored and handled without the need for additional moisture protection, simplifying logistics and storage.
• REACH Status: The LM393NG is REACH unaffected, indicating compliance with the European Union's Registration, Evaluation, Authorization, and Restriction of Chemicals (REACH) regulations.

LM393NG Applications

The LM393NG's versatility makes it ideal for various applications, including:

• Industrial Control Systems: Due to its ability to handle a wide range of supply voltages and its low power consumption, the LM393NG is well-suited for use in industrial control systems where reliability and efficiency are paramount.
• Sensor Signal Processing: The LM393NG's low input bias current and low quiescent current make it an excellent choice for processing signals from sensors in applications such as temperature monitoring or pressure sensing.
• Audio and Video Equipment: In audio and video equipment, the LM393NG can be used for signal comparison and level detection, benefiting from its general-purpose nature and robust performance.

Conclusion of LM393NG

While the LM393NG is an obsolete product, it still offers a robust solution for applications requiring a general-purpose comparator with a wide operating temperature range and flexible power supply options. Its low input bias current and quiescent current make it suitable for low-power applications, and its compliance with REACH and MSL ratings simplify its integration into various systems. Despite its obsolescence, the LM393NG remains a reliable choice for applications where these specific features are required.
