Overview
The LM124AWRQMLV is a radiation-hardened, quadruple operational amplifier manufactured by Texas Instruments. Designed for space applications, it features a bipolar architecture with four independent channels in a 14-lead ceramic flatpack (CFP) package. The device operates over an extended temperature range of -55°C to +125°C and supports a total supply voltage up to 32V. It offers a typical gain-bandwidth product of 1 MHz and a slew rate of 1 V/µs, ensuring reliable performance in high-radiation environments.
Feature Summary
- Radiation hardened for space applications
- Quadruple operational amplifier configuration
- Extended military temperature range operation
- Bipolar architecture for robust performance
Applications
- Spacecraft instrumentation systems
- Satellite communication equipment
- High-reliability aerospace sensors
- Military avionics signal processing
Procurement Notes
Verify the specific QMLV qualification status and radiation tolerance levels directly with Texas Instruments or authorized distributors. Ensure the ordering suffix matches the required lead frame and seal type for your specific environmental constraints. Confirm availability of the 14-CFP package variant as supply may be limited compared to commercial equivalents.
Selection Notes
Select this component when radiation hardness is critical for mission success. Compare the 1 MHz bandwidth and 1 V/µs slew rate against system requirements. Verify that the 14-lead CFP footprint fits the PCB layout. Consider the input bias current and offset voltage specifications for precision analog front-end designs operating in extreme temperatures.
Part Context
This part belongs to the LM124 family of quad operational amplifiers, specifically tailored for harsh environments. Unlike standard commercial variants, the AWRQMLV designation indicates compliance with strict military and space standards. It shares functional similarities with other LM124 derivatives but differs significantly in packaging and radiation hardening capabilities.
Replacement Considerations
Official substitutes include other Texas Instruments radiation-hardened op-amps such as the LM124J/PB or LM124AJ-PB if commercial grade is acceptable. For direct replacements within the QMLV line, verify pin compatibility with existing 14-CFP footprints. No cross-brand substitutes are officially confirmed without extensive validation.
