LM392D

Overview

The LM392D is a dual low-power operational amplifier and voltage comparator manufactured by Texas Instruments. It integrates two independent amplifiers within a single SOIC-8 package, designed for applications requiring both signal conditioning and threshold detection. The device operates on a supply voltage range of 3V to 30V, supporting versatile power configurations. It features a typical response time of 1.3μs and an output current capability of 2.5mA. The component functions reliably across a standard industrial temperature range from 0°C to 70°C.

Feature Summary

• Combines dual operational amplifier and voltage comparator functionalities in a single integrated circuit
• Provides open-collector outputs compatible with CMOS and TTL logic families
• Designed for low-power consumption suitable for battery-operated systems

Applications

• Voltage monitoring circuits
• Threshold detection systems
• Low-power analog signal processing

Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and material compliance. Ensure the ordering code matches the required surface-mount configuration. Cross-reference manufacturer documentation for any recent lifecycle status changes or alternative recommendations.

Selection Notes

Select this component when dual functionality is required without increasing board space. Consider the open-collector output limitation for interface compatibility. Evaluate the 1.3μs response time against system speed requirements. Confirm that the 30V maximum supply voltage aligns with the target application's power rails.

Part Context

This part belongs to the LM39x series of mixed-signal components. It serves as a cost-effective solution for designs needing both amplification and comparison. The SOIC-8 package facilitates automated assembly. It is distinct from pure op-amp or pure comparator variants by offering both functions in one housing.

Replacement Considerations

Check for LM392DR or LM392N/NOPB equivalents based on package preference. Verify pinout compatibility before substitution. Review updated datasheets for any parameter variations between legacy and current production batches.
