LM124W/883

Overview

The LM124W/883 is a military-grade, low-power quad operational amplifier manufactured by National Semiconductor. It features four independent, internally frequency-compensated amplifiers designed for wide supply voltage ranges of 3V to 32V single or ±1.5V to ±16V dual supplies. Key electrical parameters include a gain-bandwidth product of 1.2 MHz, a slew rate of 0.5 V/µs, and a maximum input offset voltage of 7 mV. The device operates within a temperature range of -55°C to +125°C and utilizes a 14-lead ceramic flatpack (DFP) package.

Feature Summary

• Military-grade reliability with MIL-STD-883 screening
• Low power consumption suitable for battery applications
• Wide single-supply operation capability including ground sensing

Applications

• Precision transducer amplifiers
• High-gain DC amplification modules
• Active filter circuits

Procurement Notes

Verify the specific revision level and lot traceability documentation when sourcing this component. Ensure that the ceramic flatpack package integrity is intact, as hermetic seals are critical for maintaining the specified military-grade performance standards under extreme environmental conditions.

Selection Notes

Select this component for designs requiring high reliability in harsh environments where standard commercial parts may fail. Consider the trade-off between its moderate bandwidth and low power consumption against higher-speed alternatives if signal processing speed is a primary constraint.

Part Context

This part belongs to the LM124 family of quad operational amplifiers, distinguished by its ruggedized construction and extended temperature range compared to commercial variants. It serves as a robust solution for aerospace and defense electronics where long-term stability and resistance to environmental stressors are mandatory requirements.
