Overview
The LM124AWGRQMLV is a quad operational amplifier manufactured by Texas Instruments, originally developed under National Semiconductor. It features four independent high-gain amplifiers with internal frequency compensation, designed for wide supply voltage ranges from 3V to 32V single supply or ±1.5V to ±16V dual supply. The device offers a gain-bandwidth product of 1.2 MHz and a slew rate of 0.5 V/µs. It operates within a temperature range of -55°C to +125°C and utilizes an 8-WFDFN (No Lead) surface-mount package.
Feature Summary
- Quad architecture with four independent, internally frequency-compensated operational amplifiers
- Wide single-supply voltage operation capability ranging from 3V to 32V
- Military-grade reliability qualification through QML classification
- Input common-mode voltage range includes ground potential
Applications
- Sensor signal conditioning in harsh environments
- DC gain modules requiring stable low-frequency performance
- Single-supply systems operating at +5V or higher voltages
- Avionics and defense electronics circuits
Procurement Notes
Verify the specific suffix 'QMLV' against the manufacturer's current datasheet to confirm exact military qualification standards and lot traceability requirements. Ensure the ordering part number matches the required tape-and-reel packaging specifications for automated assembly processes.
Selection Notes
Select this component when military-grade reliability is mandatory alongside standard quad op-amp functionality. Consider the WDFN package constraints for thermal management and PCB layout compared to traditional DIP packages. Verify that the 1.2 MHz bandwidth meets the system's signal processing speed requirements.
Part Context
This device belongs to the LM124 family of low-power quad operational amplifiers. While the base LM124 series is widely used in commercial applications, the QMLV suffix indicates a specialized variant qualified for aerospace and defense sectors, ensuring higher manufacturing controls and long-term availability.
Replacement Considerations
Direct replacements include other QML-qualified quad op-amps such as the LM124AQML or LM124BQML. Standard commercial equivalents like the LM124DRG4 may function electrically but lack the required military certification and environmental testing data.
