LM124 MDR

Overview

The LM124 MDR is a quad operational amplifier die manufactured by Texas Instruments, designed for space-rated applications. It utilizes a bipolar architecture and features a typical gain-bandwidth product of 1 MHz with a slew rate of 1 V/us. The device operates within an extended temperature range of -55 to 125 degrees Celsius and withstands total ionizing dose radiation up to 100 krad. Key electrical specifications include a maximum input offset voltage of 2 mV at 25°C, a typical common-mode rejection ratio of 85 dB, and a supply current of 0.175 mA per channel.

Feature Summary

Space-rated qualification for radiation environments
Bipolar operational amplifier architecture
Extended industrial temperature operation

Applications

Space electronics systems
Radiation-hardened signal conditioning
High-reliability analog processing

Procurement Notes

Verify the specific procurement status of the bare die variant, as availability differs from packaged equivalents. Confirm that the ordering suffix aligns with the required radiation hardness level and package group specifications. Ensure compatibility with existing flip-chip or wire-bond assembly processes intended for this component type.

Selection Notes

Select this component when space-rated reliability and radiation tolerance are mandatory requirements. The bipolar architecture offers distinct performance characteristics compared to CMOS alternatives in the same family. Verify that the 1 MHz bandwidth and 1 V/us slew rate meet the specific signal processing demands of the target application circuit design.

Part Context

This part belongs to the LM124 series of quad operational amplifiers produced by Texas Instruments. While standard commercial versions utilize SOIC or CDIP packages, the MDR designation indicates a die configuration intended for specialized packaging or hybrid integration. It shares core functional similarities with other members of the LMx24 family but is distinguished by its specific environmental ratings.
