REF2925AIDBZRG4

Overview

The REF2925AIDBZRG4 is a CMOS series voltage reference manufactured by Texas Instruments, delivering a fixed output of 2.5 V. It features an initial accuracy of 2% and a temperature coefficient of 100 ppm/°C. The device operates within an input voltage range up to 5.5 V and supports a maximum shunt current of 25 mA. Quiescent current consumption is typically 42 µA, with a maximum rating of 50 µA. It functions reliably across an extended temperature range from -40°C to +125°C. The component is housed in a compact SOT-23-3 surface-mount package.

Feature Summary

• CMOS-based series voltage reference architecture for low power operation
• Fixed 2.5 V output with 2% initial accuracy tolerance
• Extended industrial temperature stability rated to 125°C

Applications

• Photodiode signal conditioning circuits
• Power supply reference sources
• Data acquisition system references

Procurement Notes

Verify the specific suffix 'G4' indicates compliance with RoHS directives and lead-free manufacturing standards as per Texas Instruments documentation. Confirm the package marking and pinout alignment with the SOT-23-3 mechanical outline before integration. Ensure the ordering quantity matches the reel or cut tape specifications provided by the distributor to avoid packaging discrepancies during assembly.

Selection Notes

Select this component when a stable 2.5 V reference is required with moderate precision (2%) and low quiescent current. It is suitable for applications where a 100 ppm/°C temperature drift is acceptable. Compare against higher precision alternatives like the REF30xx series if tighter accuracy is needed. Ensure the load current does not exceed the 25 mA maximum shunt limit.

Part Context

This part belongs to the REF2925 family of CMOS voltage references from Texas Instruments. It shares architectural similarities with other devices in the series, such as the REF2912, but provides a distinct 2.5 V output level. The G4 suffix denotes environmental compliance, specifically regarding lead content and halogen levels, aligning with modern manufacturing standards.

Replacement Considerations

The REF2925AIDBZR serves as a functional equivalent without the G4 suffix. Other members of the REF29xx series may be considered if different voltage outputs are required while maintaining similar package and performance characteristics.
