LM392DGKTG4

Overview

The LM392DGKTG4 is a low-power operational amplifier and voltage comparator manufactured by Texas Instruments. It integrates two independent op amps and one comparator within a single package, featuring an internal reference voltage. The device operates with a supply voltage range of 2V to 36V or ±1V to ±18V. It utilizes a VSSOP-8 surface-mount package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates dual operational amplifiers and a single voltage comparator in one compact package
• Includes an internal precision reference voltage for simplified circuit design
• Supports wide single-supply or split-supply operation ranges

Applications

• Battery-powered monitoring systems
• Temperature sensing circuits
• Threshold detection applications

Procurement Notes

Verify the component status as the LM392 family has faced discontinuation notices from Texas Instruments. Confirm that the specific suffix DGKTG4 matches the required VSSOP-8 package and lead-free specifications. Ensure compatibility with existing PCB footprints before finalizing procurement decisions.

Selection Notes

Select this component when space constraints require combining multiple analog functions into a single IC. It is suitable for designs needing both signal amplification and threshold comparison alongside a stable reference source. Consider the low power consumption characteristics for battery-operated portable devices requiring minimal quiescent current.

Part Context

This part belongs to the LM392 series, which combines op amp and comparator functionalities. It serves as a cost-effective solution for reducing bill-of-materials count in mixed-signal applications. The device replaces discrete solutions by integrating essential analog blocks into a unified semiconductor structure.

Replacement Considerations

Check for direct replacements such as LM392M/NOPB or LM392N/NOPB. Verify pinout compatibility and electrical parameter equivalence before substituting.
