LM392DGKT

Overview

The LM392DGKT is a low-power operational amplifier and voltage comparator manufactured by Texas Instruments. It features a wide power-supply voltage range, supporting single supply operation from 3 V to 32 V. The device offers an excellent speed-to-power combination, making it suitable for automotive applications. Key electrical characteristics include a low output saturation voltage of 250 mV at 4 mA and a low input bias current of 400 nA. It is housed in an 8-VSSOP package.

Feature Summary

• Low-power design with excellent speed-to-power ratio
• Wide single-supply voltage range from 3 V to 32 V
• Low output saturation voltage of 250 mV at 4 mA
• Qualified for automotive applications

Applications

• Automotive electronic systems
• Transducer amplification
• Voltage monitoring circuits

Procurement Notes

Verify the specific suffix DGKT corresponds to the 8-VSSOP package when ordering. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the component meets AEC-Q100 automotive qualification requirements if used in automotive environments. Cross-reference part numbers carefully to distinguish between standard and automotive grades.

Selection Notes

Select this component for designs requiring low power consumption alongside moderate speed. The wide supply voltage range allows flexibility in system architecture. Consider the VSSOP package size for space-constrained PCB layouts. Verify thermal performance within the operating temperature range for the specific application environment.

Part Context

The LM392 series combines an operational amplifier and a voltage comparator in a single package. The LM392DGKT variant specifically utilizes the VSSOP-8 package format. This integration reduces component count and board space compared to using separate devices. The series is designed for efficiency in analog signal processing tasks.

Replacement Considerations

Check for direct pin-compatible alternatives within the same family. Verify that substitute components meet the same automotive qualification standards if required. Ensure equivalent electrical parameters such as supply voltage range and output characteristics are maintained.
