LM392M

Overview

The LM392M is a dual low-power operational amplifier and voltage comparator manufactured by Texas Instruments. It integrates two independent amplifiers within a single 8-pin SOIC package, designed for applications requiring both signal conditioning and threshold detection. The device operates within a supply voltage range of 3V to 32V and supports an output current of 40mA at 5V. Key electrical characteristics include a bandwidth of 1 MHz, a slew rate of 100 mV/µs, and a maximum input offset voltage of 7 mV. It functions reliably across a temperature range of 0°C to 70°C with a static current consumption of 500 µA.

Feature Summary

• Integrates dual operational amplifiers and voltage comparators in a compact surface-mount package
• Supports wide single-supply voltage operation from 3V to 32V
• Provides high output drive capability suitable for direct sensor interfacing

Applications

• Sensor signal amplification and conditioning
• Voltage threshold detection circuits
• Low-power analog signal processing

Procurement Notes

Verify component authenticity through authorized channels as the LM392M has reached end-of-life status. Confirm that replacement units match the original pinout and electrical specifications. Ensure compliance with RoHS3 standards if required by the design. Check for available direct substitutes like the LM392M/NOPB to maintain supply continuity.

Selection Notes

Select this component for designs requiring combined amplification and comparison functions without occupying excessive board space. Consider the 8-SOIC package constraints for thermal management and layout. Evaluate the 1 MHz bandwidth against signal frequency requirements. Verify that the 0°C to 70°C operating range meets environmental conditions.

Part Context

The LM392M belongs to the LM392 family of mixed-signal integrated circuits produced by Texas Instruments. It combines linear amplifier performance with digital comparator functionality. The device utilizes standard bipolar technology to achieve low power consumption while maintaining adequate speed for general-purpose analog applications.

Replacement Considerations

The LM392M/NOPB is a confirmed direct substitute offering identical functionality and pin compatibility. Verify lead-free compliance and packaging variations when transitioning to the replacement part.
