LM124AWRLQMLV

Overview

The LM124AWRLQMLV is a quadruple operational amplifier manufactured by Texas Instruments, designed for high-reliability applications. It features a wide supply voltage range from 3 V to 32 V and operates across an extended temperature range of -55°C to 125°C. The device integrates four independent amplifiers within a single package, offering a gain-bandwidth product of 1 MHz and a slew rate of 0.5 V/µs. It supports rail-to-rail output swing toward the negative supply and includes internal frequency compensation for stability in various configurations.

Procurement Notes

Verify the specific QML qualification status and lot traceability requirements directly with the manufacturer or authorized distributors. Ensure that the ordering suffix matches the exact radiation hardness and screening level needed for your mission-critical design. Confirm package availability and lead times through official TI channels prior to finalizing procurement plans.

Selection Notes

Select this component when multiple low-power op-amps are required in a compact form factor. Consider its 1 MHz bandwidth and 0.5 V/µs slew rate for moderate-speed applications. Evaluate the input offset voltage and bias current specifications against your circuit's precision requirements. Ensure the supply voltage constraints align with your system's power budget.

Part Context

This part belongs to the LM124 family of low-power quad operational amplifiers produced by Texas Instruments. The QMLV designation indicates it meets specific military or aerospace quality standards. It shares core electrical characteristics with other LM124 variants but differs in packaging and reliability screening levels suitable for space or defense applications.

Replacement Considerations

Official substitutes include other LM124 variants such as LM124AJQMLV or LM124AQMLV, provided they meet the same radiation and screening requirements. Verify pinout compatibility and thermal performance before substitution. Consult the manufacturer for approved replacement lists to ensure continued compliance with quality standards.
