LM124AJ/883/MABI

Overview

The LM124AJ/883/MABI is a military-grade, quadruple operational amplifier manufactured by Texas Instruments. It features four independent high-gain amplifiers with internal frequency compensation, designed for single or split power supply operation. The device operates within a wide voltage range of 3V to 32V and supports an extended temperature range from -55°C to 125°C. Key electrical characteristics include a gain-bandwidth product of 1.2 MHz, a slew rate of 500 mV/us, and low input bias current. It is housed in a 14-lead ceramic dual in-line package (CDIP) suitable for through-hole mounting.

Feature Summary

• Military-grade reliability compliant with MIL-STD-883 standards
• Low power consumption with supply current independent of voltage magnitude
• Input common mode voltage range includes ground potential
• Wide single-supply operating voltage range up to 32V

Applications

• Precision data acquisition systems requiring high reliability
• Industrial control circuits operating in extreme temperatures
• Medical instrumentation with strict component qualification needs
• Aerospace signal conditioning and filtering applications

Procurement Notes

Verify the specific MABI suffix requirements against the official manufacturer datasheet to ensure compliance with military quality standards. Confirm that the CDIP-14 ceramic package matches the mechanical constraints of the target design. Cross-reference the lot traceability and testing reports required for defense or aerospace procurement protocols.

Selection Notes

Select this component when standard commercial op-amps fail to meet environmental or reliability specifications. The LM124AJ offers superior performance over the LM324 series in terms of offset voltage and bias current. Ensure the design accounts for the thermal dissipation capabilities of the ceramic package under maximum load conditions.

Part Context

This part belongs to the LM124 family of low-power quad operational amplifiers. It shares functional similarities with the LM224 and LM324 but is distinguished by its military-grade screening and packaging. The device is part of Texas Instruments' long-standing portfolio of analog integrated circuits designed for robust performance in demanding environments.

Replacement Considerations

Official substitutes include other military-qualified variants within the LM124 family such as the LM124AJ/NOPB if available in compatible packaging. Verify pin compatibility and electrical parameter tolerances before substitution. Consult the manufacturer's obsolescence notices for alternative recommendations.
