LM124AJRQMLV

Overview

The LM124AJRQMLV is a quadruple operational amplifier manufactured by Texas Instruments, designed for high-reliability applications. It features four independent amplifiers within a single package, offering a gain-bandwidth product of 1 MHz and a slew rate of 0.5 V/us. The device operates with a supply voltage range from 3 V to 32 V and supports an operating temperature range from -55°C to 125°C. It is housed in a surface-mount SOIC-14 package, providing low input bias current and high common-mode rejection ratio for precision signal processing.

Feature Summary

• Quadruple operational amplifier configuration for multi-channel signal conditioning
• Qualified for military and aerospace environments ensuring high reliability
• Wide single or dual power supply operation capability
• High common-mode rejection ratio for accurate differential measurements

Applications

• Aerospace guidance and navigation systems
• Military communication equipment signal processing
• Spacecraft telemetry data acquisition
• Harsh environment industrial control systems

Procurement Notes

Verify the specific QML qualification level and lot traceability requirements before procurement. Ensure that the supplier provides full documentation regarding environmental screening and testing standards. Confirm that the component meets all necessary military specifications for the intended application environment.

Selection Notes

Select this component when high reliability and radiation tolerance are critical. Compare against standard commercial grades if cost is a primary constraint and environmental conditions are less severe. Consider the SOIC-14 package constraints for PCB layout and thermal management in dense assemblies.

Part Context

This part belongs to the LM124 family of quadruple operational amplifiers, specifically tailored for ruggedized applications. It shares functional similarities with other LM124 variants but distinguishes itself through enhanced manufacturing controls and qualification processes suitable for defense and space sectors.

Replacement Considerations

Direct replacements must match the QML qualification status. Verify pin compatibility with existing designs. Evaluate thermal performance and electrical parameters against the original specification to ensure no degradation in system performance during substitution.
