Overview
The REF3325AIDBZR is a precision series voltage reference manufactured by Texas Instruments, housed in an SOT-23-3 surface-mount package. It provides a fixed output voltage of 2.5 V with an initial accuracy of 0.15%. The device exhibits a temperature coefficient of 30 ppm/°C and operates within an input voltage range up to 5.5 V. It draws a typical quiescent current of 3.9 µA and supports a maximum shunt current of 5 mA. The component functions reliably across an extended industrial temperature range from -40°C to +125°C.
Feature Summary
- Provides stable 2.5 V reference output with high initial accuracy
- Low power consumption suitable for battery-operated systems
- Compact SOT-23-3 footprint for space-constrained designs
Applications
- Precision analog-to-digital converter (ADC) references
- Data acquisition systems requiring stable voltage sources
- Portable instrumentation powered by single supplies
Procurement Notes
Verify the specific suffix 'DBZR' corresponds to the reel packaging configuration required for your assembly line. Confirm RoHS compliance status through the official datasheet as indicated in manufacturer specifications. Ensure moisture sensitivity level requirements are met during storage and handling procedures prior to soldering.
Selection Notes
Select this component when a fixed 2.5 V output is required with tight tolerance and low drift over temperature. Consider the 3.9 µA quiescent current for power-sensitive applications. Verify that the SOT-23-3 package fits the PCB layout constraints and that the 5.5 V maximum input voltage aligns with the system supply rails.
Part Context
This part belongs to the REF3325 family of precision voltage references from Texas Instruments. It shares core electrical characteristics with other variants in the series but differs in packaging and tape-and-reel specifications. The 'A' grade indicates tighter initial accuracy compared to standard grades, ensuring higher precision for critical measurement applications.
Replacement Considerations
The REF3325AIDBZT serves as a cut-tape alternative offering identical electrical performance. The REF3325AIDBZRG4 is a legacy version with similar specifications but may be subject to end-of-life status; verify current availability and lead times before substitution.
