LM124AWRLQMLV

Overview

The LM124AWRLQMLV is a quadruple operational amplifier manufactured by National Semiconductor, designed for high-reliability applications. It features a bipolar architecture and operates within an extended temperature range of -55°C to 125°C. The device provides four independent channels with a typical gain-bandwidth product of 1 MHz and a slew rate of 1 V/µs. It supports a total supply voltage range from 3 V to 32 V. Key electrical specifications include a maximum input offset voltage of 2 mV at 25°C and a minimum common-mode rejection ratio of 70 dB. The component is housed in a 14-lead ceramic flatpack (CFP) package.

Feature Summary

• Radiation-hardened design suitable for space environments
• ELDRS-free bipolar low dropout regulator compatibility
• Extended military-grade temperature operation

Applications

• Spacecraft power management systems
• High-reliability analog signal processing
• Military avionics instrumentation

Procurement Notes

Verify the specific radiation tolerance levels and ELDRS-free status against the official datasheet before integration. Confirm that the CFP-14 package dimensions match the target PCB footprint. Ensure the supplier provides traceability documentation required for aerospace or defense procurement standards.

Selection Notes

Select this component when radiation hardness and wide temperature stability are critical. It serves as a robust alternative to standard commercial op-amps in harsh environments. Consider the 1 MHz bandwidth and low power consumption for battery-operated satellite payloads requiring precise signal conditioning.

Part Context

This part belongs to the LM124 family of low-power quad operational amplifiers. While the standard LM124 is a commercial device, the LQMLV suffix indicates a qualified military or space-grade variant. It shares functional similarities with the LM2941 regulator regarding radiation testing methodologies but differs in application as an active signal amplifier rather than a voltage regulator.
