LM124J/883/MABI

Overview

The LM124J/883/MABI is a military-grade, low-power quad operational amplifier manufactured by Texas Instruments. It features four independent, high-gain, internally frequency-compensated amplifiers designed for wide single-supply voltage ranges from 3V to 32V or dual supplies of ±1.5V to ±16V. The device operates within a temperature range of -55°C to +125°C and utilizes a 14-lead ceramic dual in-line package (CDIP). Key electrical characteristics include a gain-bandwidth product of 1.2 MHz, a slew rate of 0.5 V/µs, and an input offset voltage maximum of 7 mV. This component meets MIL-STD-883 requirements for enhanced reliability in demanding environments.

Feature Summary

• Military-grade construction compliant with MIL-STD-883 standards
• Low power consumption suitable for battery-operated systems
• Wide single-supply voltage operation capability
• Internally frequency compensated for stability

Applications

• Precision sensor signal conditioning
• Industrial control system interfaces
• Aerospace instrumentation circuits
• High-reliability data acquisition modules

Procurement Notes

Verify the specific MABI suffix details against the official Texas Instruments datasheet to confirm exact screening levels and testing parameters required for your application. Ensure that the procurement source provides valid traceability documentation consistent with military specifications.

Selection Notes

Select this component when military reliability and wide temperature operation are critical. Compare the CDIP package constraints against available board space. Consider the 1.2 MHz bandwidth limits for high-speed signal processing requirements before finalizing the design.

Part Context

This part belongs to the LM124 family of low-power quad operational amplifiers originally developed by National Semiconductor and now produced by Texas Instruments. The /883 designation indicates compliance with MIL-STD-883, distinguishing it from commercial variants like the LM124J/NOPB. It serves as a robust solution for harsh environment electronics where standard commercial parts may fail.

Replacement Considerations

Official substitutes include other MIL-STD-883 qualified versions within the LM124 series. Verify pin compatibility and electrical parameter overlaps with any alternative military-grade quad op-amps before implementation.
