LM336DG4-2-5

Overview

The LM336DG4-2-5 is a precision shunt voltage reference integrated circuit manufactured by Texas Instruments. It provides a fixed output voltage of 2.49 V with an initial accuracy of ±4%. The device operates within a temperature range of 0°C to 70°C and features a temperature coefficient of 10 mV/°C. It supports a maximum shunt current of 10 mA and is housed in an 8-SOIC package.

Feature Summary

• Provides a stable, fixed 2.49 V reference voltage for precision applications
• Utilizes shunt topology for efficient regulation in series configurations
• Ensures reliable performance across standard industrial operating temperatures

Applications

• Precision analog-to-digital converter (ADC) reference sources
• Data acquisition system voltage references
• Instrumentation amplifier biasing circuits

Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS status as per manufacturer documentation. Confirm the 8-SOIC package dimensions match the target PCB footprint. Ensure the ±4% accuracy meets the system tolerance requirements before finalizing procurement orders.

Selection Notes

Select this component when a fixed 2.49 V reference is required in surface-mount form factor. Compare against LM336Z variants if through-hole mounting is preferred. Consider the 10 mA current limit for load driving capabilities and verify thermal management needs within the 0°C to 70°C operational window.

Part Context

This part belongs to the LM336 family of two-terminal voltage references. It serves as a surface-mount alternative to the TO-92 packaged LM336Z series. The device integrates the reference diode and compensation components into a single compact IC suitable for automated assembly processes.

Replacement Considerations

LM336BDR-2.5 offers similar functionality in an SOIC package but may differ in specific electrical tolerances or packaging details.
