LM124AWGRLQMLV

Overview

The LM124AWGRLQMLV is a radiation-hardened, quadruple operational amplifier manufactured by Texas Instruments under the QMLV qualification standard. It features four independent high-gain amplifiers with internal frequency compensation, designed for space applications requiring tolerance to total ionizing dose and single-event effects. The device operates from split power supplies and maintains low-power supply current drain independent of voltage magnitude. It utilizes a 14-lead ceramic flatpack (CFP) package to ensure reliability in harsh environments.

Feature Summary

• Radiation-hardened design qualified to QMLV standards
• Quadruple operational amplifier configuration with internal frequency compensation
• Operates from split power supplies with low power consumption
• High gain bandwidth and large voltage gain capabilities

Applications

• Low Earth Orbit satellite instrumentation
• Deep space exploration systems
• Spacecraft telemetry and control circuits
• Harsh environment signal conditioning

Procurement Notes

This component is a specialized aerospace-grade part subject to strict quality controls. Availability is limited and often requires direct engagement with the manufacturer or authorized distributors specializing in military/aerospace components. Verify specific lot traceability and test reports required for mission-critical implementations.

Selection Notes

Select this part when radiation hardness is mandatory for space missions. Compare against commercial LM124 variants if environmental shielding is sufficient. Ensure the 14-lead CFP package fits the mechanical constraints of the target PCB or hybrid microcircuit assembly.

Part Context

The LM124 series represents a legacy line of general-purpose quad op-amps adapted for extreme environments. The QMLV suffix indicates qualification under the Qualified Manufacturing Line V program, ensuring enhanced screening and testing beyond standard industrial specifications for space flight hardware.

Replacement Considerations

Direct replacements are limited due to the specific QMLV qualification. Evaluate other TI radiation-hardened op-amps such as the LM124AQMLV or LM124BQMLV if pin compatibility and electrical parameters align with the original design requirements.
