Overview
The REF3325AIDCKT is a series voltage reference from Texas Instruments, housed in an SC-70-3 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 operating supply current of 3.9 µA and supports a maximum shunt current of 5 mA. The component functions reliably across an extended temperature range from -40°C to +125°C.
Feature Summary
- Delivers stable 2.5 V reference output with high initial accuracy
- Low power consumption suitable for battery-operated systems
- Compact SC-70-3 footprint for space-constrained designs
Applications
- Portable instrumentation requiring precise voltage standards
- Data acquisition systems needing stable reference sources
- Battery-powered devices optimizing power efficiency
Procurement Notes
Verify the specific suffix 'CKT' corresponds to the Cut Tape packaging format when ordering. Confirm that the SC-70-3 package dimensions match your PCB layout requirements. Ensure compatibility with the 2.5 V output level for your target circuit design. Check humidity sensitivity handling procedures during assembly.
Selection Notes
Choose this component when a low-power, compact voltage reference is required. The 3.9 µA current draw makes it ideal for energy-efficient applications. The 0.15% initial accuracy ensures precision without complex calibration. Verify that the 5.5 V maximum input voltage aligns with your system's supply rails.
Part Context
This part belongs to the REF3325 family of precision voltage references manufactured by Texas Instruments. It shares core electrical specifications with other variants in the series but differs in packaging and reel configuration. The REF3325AIDCKR variant offers identical performance in a Reel format.
Replacement Considerations
The REF3325AIDCKR is a direct functional substitute with identical electrical characteristics, differing only in packaging format (Reel vs. Cut Tape). Other REF3325 variants may share pinouts but require verification of output voltage and package type.
