LM2924M

Overview

The LM2924M is a dual operational amplifier manufactured by National Semiconductor, now part of Texas Instruments. It features a gain-bandwidth product of 1 MHz and a slew rate of 0.5 V/µs. The device operates with an input offset voltage of 7 mV and an input bias current of 250 nA. It supports a supply voltage range from 3 V to 26 V single supply or ±1.5 V to ±13 V dual supply. The component is housed in an SOIC-8 surface-mount package and functions as a low-power amplifier.

Feature Summary

• Dual operational amplifier architecture designed for single-supply operation
• Internally frequency compensated for unity-gain stability
• Low power consumption characteristics suitable for battery applications

Applications

• General-purpose analog signal conditioning circuits
• Active filter implementations
• Voltage follower configurations

Procurement Notes

Verify the manufacturer designation carefully, as National Semiconductor assets were acquired by Texas Instruments. Confirm that the suffix /NOPB indicates lead-free and RoHS compliance if required by your assembly specifications. Ensure the package type matches the SOIC-8 footprint on your PCB layout. Check for any specific temperature grade requirements within the commercial range.

Selection Notes

Select this component when a dual op-amp solution is needed for low-cost, general-purpose applications requiring single-supply compatibility. It is appropriate for designs where moderate bandwidth and low quiescent current are prioritized over high-speed performance. Consider alternative packages if higher pin counts or different thermal properties are necessary for the enclosure design.

Part Context

This device belongs to the broader family of low-power quad and dual operational amplifiers produced by National Semiconductor. These components are widely used in industrial and consumer electronics due to their versatility and cost-effectiveness. The LM2924 series provides a reliable solution for basic amplification tasks without the complexity of high-speed precision amplifiers.

Replacement Considerations

The LM2904M/NOPB is a documented substitute offering similar dual op-amp functionality and electrical characteristics. Verify pinout compatibility and package dimensions before substituting to ensure mechanical fit.
