LM124 MDE

Overview

The LM124 MDE is a quad operational amplifier manufactured by Texas Instruments, designed for low-power applications. It features four independent high-gain amplifiers with internal frequency compensation. The device operates on a wide supply voltage range of 3V to 32V single supply or ±1.5V to ±16V dual supply. Key electrical parameters include a gain-bandwidth product of 1.2 MHz, a slew rate of 500 mV/µs, and an input offset voltage of 7 mV. It draws a typical operating supply current of 4 mA and provides an output current of 10 mA per channel. The unit offers a common-mode rejection ratio of 80 dB and an input voltage noise density of 35 nV/√Hz.

Feature Summary

• Four independent high-gain operational amplifiers with internal frequency compensation
• Wide single-supply operation capability from 3V to 32V
• Input common-mode voltage range includes ground potential

Applications

• Sensor signal conditioning
• DC gain modules
• General-purpose analog circuits

Procurement Notes

Verify the specific suffix 'MDE' against official Texas Instruments documentation to confirm package type and material composition. Ensure compatibility with required thermal management and mounting standards. Cross-reference datasheet revisions to confirm parameter consistency. Confirm RoHS compliance status if required for the application environment.

Selection Notes

Select this component for designs requiring low power consumption with wide voltage flexibility. The inclusion of ground in the common-mode range simplifies single-supply interfacing. Verify that the 1.2 MHz bandwidth meets signal processing requirements. Consider the CDIP or CFP package options if hermetic sealing or through-hole mounting is necessary for the target system.

Part Context

The LM124 series belongs to Texas Instruments' family of low-power quad operational amplifiers. Originally developed by National Semiconductor, the line continues under TI. The LM124 variant specifically targets military and aerospace environments, offering extended temperature ranges and radiation tolerance compared to commercial counterparts like the LM324.
