Overview
The REF3325AIDCKRG4 is a precision series voltage reference from Texas Instruments, delivering a fixed output of 2.5 V with an initial accuracy of ±0.15%. It operates within an input voltage range of 2.7 V to 5.5 V and consumes a typical supply current of 3.9 µA. The device features a low temperature coefficient of 30 ppm/°C and supports a maximum load current of 5 mA. Housed in a compact SC-70-3 surface-mount package, it 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
- Ultra-low power consumption suitable for battery-operated systems
- Compact SC-70-3 footprint for space-constrained designs
Applications
- Portable instrumentation requiring precise voltage references
- Battery-powered measurement devices
- Data acquisition systems
Procurement Notes
Verify the specific suffix 'G4' indicates RoHS compliance and lead-free construction as per manufacturer standards. Confirm the SC-70-3 package type matches your PCB footprint requirements. Ensure the 2.5 V output aligns with your system's reference needs. Check for any moisture sensitivity level restrictions during storage and handling.
Selection Notes
Select this component when a fixed 2.5 V reference is required with tight accuracy tolerances. The low quiescent current makes it ideal for energy-efficient applications. Consider the SC-70-3 package size for board space limitations. Verify that the 5 mA load capability meets your circuit's drive requirements.
Part Context
This part belongs to the REF33xx family of precision voltage references from Texas Instruments. It shares core specifications with other variants like the REF3325AIDCKT but differs in packaging and compliance markings. The 'G4' suffix typically denotes Green/RoHS-compliant manufacturing processes.
Replacement Considerations
Direct substitutes include REF3325AIDCKT and REF3325AIDCKR, which share identical electrical characteristics and pinouts. Alternative packages such as SOT-23-3 (REF3325AIDBZ) offer different form factors with similar performance.
