REF3025AIDBZTG4

Overview

The REF3025AIDBZTG4 is a precision series voltage reference from Texas Instruments, delivering a fixed output of 2.5 V with an initial accuracy of 0.2%. It operates within a supply voltage range up to 5.5 V and supports a maximum shunt current of 25 mA. The device features a typical quiescent current of 42 µA and a temperature coefficient of 75 ppm/°C. It is housed in a compact SOT-23-3 package and functions reliably across an extended industrial temperature range from -40°C to +125°C.

Feature Summary

• Provides stable voltage reference without requiring external load capacitors for stability
• Delivers high precision with 0.2% initial accuracy and low temperature drift
• Supports high output drive capability with up to 25 mA shunt current
• Operates efficiently with ultra-low power consumption suitable for battery applications

Applications

• Loop-powered industrial sensors and transmitters
• Portable instrumentation and test equipment
• Medical devices requiring precise analog references
• Data acquisition systems and signal conditioning circuits

Procurement Notes

Verify component authenticity through authorized channels as the REF3025AIDBZTG4 variant may have specific lifecycle status. Confirm RoHS compliance details and check for obsolescence notices from Texas Instruments before finalizing procurement plans. Ensure packaging specifications match design requirements.

Selection Notes

Select this component when a fixed 2.5 V reference with 0.2% accuracy is required in a small SOT-23-3 footprint. Consider the 75 ppm/°C temperature coefficient for thermal stability needs. Evaluate the 42 µA quiescent current against system power budgets and verify input voltage compatibility within the 2.55 V to 5.5 V range.

Part Context

This part belongs to the REF30xx family of bandgap voltage references designed for low-power, high-precision applications. The 'G4' suffix typically indicates lead-free and RoHS-compliant manufacturing standards. It serves as a critical reference element in analog-to-digital conversion chains and sensor interfaces where long-term stability is essential.

Replacement Considerations

Direct substitutes include REF3025AIDBZR and REF3025AIDBZT which share identical electrical characteristics and pinout configurations. Verify that alternative packages or suffixes maintain the same 0.2% accuracy and 25 mA drive capability.
