Linear Comparators

LM319AM Description

The LM319AM is a general-purpose comparator IC designed by Texas Instruments, featuring a dual-element configuration in a 14-pin SOIC package. This obsolete yet REACH unaffected and ROHS3 compliant device offers a robust solution for various electronic applications. It operates within a temperature range of 0°C to 70°C and is suitable for surface-mount applications. The LM319AM has a maximum quiescent current of 12.5mA and a moisture sensitivity level (MSL) of 1, indicating it is not moisture sensitive and can be stored indefinitely under normal conditions.

LM319AM Features

The LM319AM boasts several notable technical specifications that make it a versatile component for a wide range of applications. It features a maximum input offset voltage of 1mV at ±15V supply, ensuring high accuracy and reliability in voltage comparison tasks. The maximum input bias current is a mere 0.5µA at ±15V, which minimizes power consumption and enhances performance in low-power applications.

The LM319AM supports a wide supply voltage range, with single supply voltages from 5V to 36V and dual supply voltages from ±2.5V to ±18V. This flexibility allows it to be used in various power supply configurations, making it suitable for both low-power and high-voltage applications. The device is packaged in a tube, which provides a convenient and reliable method for handling and storage.

LM319AM Applications

The LM319AM is ideal for applications requiring precise voltage comparison and signal processing. Its general-purpose nature makes it suitable for a variety of tasks, including level detection, window comparators, and signal conditioning. The comparator can be used in industrial control systems, where accurate voltage monitoring is essential for maintaining operational parameters within specified limits.

In consumer electronics, the LM319AM can be employed in power management circuits to monitor and control power supply voltages, ensuring stable operation and protecting sensitive components from voltage fluctuations. It is also useful in automotive applications, where it can be used to monitor battery voltage levels and trigger alerts or actions when the voltage falls outside the safe operating range.

Conclusion of LM319AM

Despite its obsolete status, the LM319AM remains a reliable and versatile comparator IC with a wide range of applications. Its low input offset voltage, low input bias current, and wide supply voltage range make it an excellent choice for precise voltage comparison tasks. The device's compliance with REACH and ROHS3 standards ensures it meets environmental and safety regulations, making it suitable for use in modern electronic designs. While newer alternatives may offer advanced features, the LM319AM continues to provide a cost-effective and reliable solution for general-purpose comparator needs.
