REF3325AIDBZRG4

Overview

The REF3325AIDBZRG4 is a fixed-output series voltage reference from Texas Instruments, providing a nominal output of 2.5 V with an initial accuracy of 0.15%. It operates within an input voltage range up to 5.5 V and supports a maximum shunt current of 5 mA. The device features a low quiescent current of 3.9 µA and a temperature coefficient of 30 ppm/°C. It is housed in a SOT-23-3 package and functions reliably across a temperature range of -40°C to +125°C.

Feature Summary

• Provides stable 2.5 V reference with high initial accuracy
• Ultra-low power consumption suitable for battery applications
• Compact surface-mount packaging for space-constrained designs

Applications

• Portable instrumentation requiring precise voltage references
• Battery-powered measurement systems
• Data acquisition channels

Procurement Notes

Verify the G4 suffix indicates lead-free compliance and RoHS adherence per manufacturer specifications. Confirm the SOT-23-3 package type matches your PCB footprint requirements. Check humidity sensitivity levels and reflow soldering profiles against assembly guidelines. Ensure the operating temperature range meets your environmental conditions.

Selection Notes

Select this component when a 2.5 V fixed reference with tight initial accuracy is required. Consider the 30 ppm/°C drift for thermal stability needs. Evaluate the 3.9 µA current draw against system power budgets. Verify compatibility with the SOT-23-3 package for layout constraints.

Part Context

This part belongs to the REF3325 family of precision voltage references. It shares core electrical characteristics with variants like REF3325AIDBZR and REF3325AIDBZT. The primary distinction lies in the packaging and tape-and-reel configuration indicated by the suffix.
