REF2925AIDBZTG4

Overview

The REF2925AIDBZTG4 is a CMOS series voltage reference manufactured by Texas Instruments, providing 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 is typically 42 µA with a maximum of 50 µA. It functions reliably across a temperature range of -40°C to +125°C and is housed in a SOT-23-3 package.

Feature Summary

• CMOS technology ensures low power consumption suitable for battery-operated systems.
• Series reference architecture provides stable output voltage over varying load conditions.
• Compact SOT-23-3 surface-mount package facilitates space-constrained PCB layouts.

Applications

• Portable instrumentation requiring precise voltage references.
• Battery-powered measurement devices.
• Data acquisition systems needing stable analog references.

Procurement Notes

Verify the G4 suffix indicates lead-free compliance and RoHS adherence per manufacturer specifications. Confirm the specific tape-and-reel or cut-tape packaging format required for your assembly process. Ensure the ordering part number matches the exact temperature grade and accuracy class needed for your design constraints.

Selection Notes

Select this component when a 2.5 V reference with 2% initial accuracy is sufficient. It is appropriate for applications where 100 ppm/°C drift is acceptable. Consider higher precision models if tighter tolerance or lower temperature coefficients are required for critical signal chain performance.

Part Context

This part belongs to the REF29xx family of low-power voltage references from Texas Instruments. It shares the same pinout and form factor as other variants in the series, such as the REF2912 and REF2933, which offer different output voltages but similar electrical characteristics and package options.

Replacement Considerations

The REF2925AIDBZR is a compatible alternative without the G4 suffix, offering identical electrical performance. Verify that any substitute maintains the same SOT-23-3 footprint and thermal characteristics for direct board replacement.
